How to choose a camera?

Question 1: How to choose a professional camera? Hello!

Compared with traditional cameras, the biggest advantage of digital cameras is that they can be seen immediately, and they can be deleted if they are dissatisfied. Another advantage is very useful for learning photography, that is, in full manual mode, you can choose the aperture value and shutter speed yourself. When you adjust an item, you can immediately see the actual effect on the LCD screen, too bright or too dark, and then adjust it according to the picture you see. These traditional cameras can't do this, they just estimate when shooting, and the real effect is only when the photos are printed.

Professional digital cameras are usually expensive, ranging from 5,000 to 6,000 yuan or even tens of thousands of yuan. Therefore, it is better to buy the best than the cheapest. This cheap is also relative. Digital cameras are generally divided into two types, SLR and traditional. The former is suitable for professionals, with interchangeable lenses, large volume, expensive price and good imaging quality. The latter is suitable for home use, basically can not change the lens, light, suitable for quick shooting, cheap, imaging quality is not as good as SLR.

Purchase suggestion:

1. The most important part of a digital camera is CCD, which is generally "1/?" ? Inch "means that the smaller the value after" 1 ",the larger the CCD size, the better the imaging quality, and11.8 inch is better.

Second, the card machine, the card machine is the biggest feature, but it is not recommended to buy a card machine, because the card machine is thin, its optical zoom factor can not be very high, at most 2 to 3 times, while the non-card machine can reach 3 to 4 times. Professional can reach 10 times or more. Optical zoom is the real zoom. Digital zoom is just a number in name only.

In order to ensure the compact body of the card machine, the lens size is generally relatively small. Anyone who knows a little about optics knows that the larger the lens size, the more light enters and the better the imaging quality. This is why professional cameras have larger lenses.

Third, don't blindly pursue the size of CCD. This is not everything. For example, the CCD of card machine is 5 million pixels, and the CCD of non-card machine is 3 million pixels. In fact, the photos taken without the card machine are still good. 4 million households is enough.

Fourth, when shopping, when representing the pixels of a digital camera, some will indicate the effective pixels, and some will indicate the interpolated pixels. Effective pixels are the real pixels of the camera, and interpolation pixels are simply pixels obtained by enlarging photos through software processing. A camera has 4 million interpolated pixels, and the actual pixels are only about 3.2 million. Don't listen to the boasting of profiteers.

I suggest you spend more time on the following websites:

pconline/digital/dc/

This is the digital camera shopping guide and evaluation column of Pacific Computer Network, which has a high reputation in China. It contains a lot of practical information, such as leaderboards, experience and so on. This is very important. It's helpful to see how others feel after using it.

After reading many articles on this website, I bought my first digital camera at that time. It's Canon A5 10. It has been used for a year, and it feels as good as the introduction. Don't be afraid of trouble. I suggest you go to the store to see the brand and model first, ask the price by the way, and then come back online to read the related articles carefully.

I wish you a satisfactory camera!

Question 2: For beginners, how to choose a suitable SLR camera? First, let's take a look at what a SLR camera is.

SLR camera is short for SLR camera. Specifically, it is a camera that uses a lens to view through a mirror.

Therefore, this paper does not discuss cameras with two lenses and cameras that do not look through the mirror. The picture below shows the Great Wall double-reflex camera, Leica paraxial camera, Canon card camera and Sony micro-camera.

As shown in the above figure, although Sony a7 is much like a SLR camera, it is not a SLR camera because it does not reflect through the lens optical path.

What are the advantages of SLR cameras over other cameras?

First of all, what you see is what you get. Because you view directly through the lens, the image you see from the viewfinder is an image obtained as a result of shooting. Secondly, the response speed is fast. The start-up speed of digital SLR is only a few hundred milliseconds. Because their focusing systems are independent of imaging equipment, they can basically achieve the same response speed as traditional SLR, making users handy in news and sports photography.

Secondly, the lens selection is convenient. Each brand has a huge autofocus lens group, from super wide angle to super telephoto, from macro to soft focus. Users can choose matching lenses according to their own needs. The picture below shows Canon lens group and Nikon lens group.

Ok, let's introduce the general situation of SLR cameras at present.

At present, the mainstream SLR cameras are mainly 135 SLR and 120 SLR. 135 SLR includes all SLR cameras of Canon Nikon. At present, 120 SLR mainly includes mamia, Pentax and Hasselblad.

In which 135 SLR is divided into aps-c format SLR and Quan Huafu SLR.

For example, Canon 1200d, 100d, 700d, 750d, 760d, 70d, 80d and 7d2, Nikon d3300, d5300 and d7200 are all aps-c format SLR. The following picture shows Canon 760d, 700d,100d; ; Nikon d3300, d5200, d7200

Canon 6d, 5d3, 5ds, 5dsr, 1dx, 1dx2, Nikon d6 10, d750, d8 10, d4 and d5 belong to Quan Huafu SLR. The following picture shows Canon 6d, 5ds,1dx; ; Nikon d4s

Generally, SLR cameras and lenses have a general classification, such as entry-level or junior, intermediate, advanced and professional.

Entry-level: Canon xxxd, xxxxd, Nikon d5xxx, dxxx, featuring light weight, high degree of automation, certain professional functions and high cost performance. The picture below shows Canon 760d and 700d；; Nikon d3300, d5200

Intermediate: Canon xxd, Nikon d7xxx, dxx, the fuselage strength is significantly improved, the shutter usage is much higher than the entry level, and it has various professional functions. The picture below shows Canon 80d；; nikon d7200

Advanced: Canon xd, Nikon d7xx, D8x, general professional fuselage with aps frame, or Quan Huafu fuselage. The fuselage has high strength and various professional functions. The picture below shows Canon 5ds；; Nikon d8 10

Professional grade: Canon 1d series and Nikon dx series, suitable for harsh shooting environment, with extremely high durability and reliability and various professional functions. The picture below shows Canon1DX; ; Nikon d4s

120 SLR belongs to a special category, and it is discussed separately at last.

Ok, let's get down to business. How to choose a suitable SLR camera?

We generally analyze it from two angles, one is according to the purpose, and the other is according to the capital budget.

First of all, use is the purpose of buying a camera.

If there is no clear shooting purpose, it is a general photo shoot or a photo shoot while traveling, it is recommended to set up an entry-level machine.

For example, Canon XXXD+/KOOC-0/8-55 or XXXD+/KOOC-0/8-/KOOC-0/35, Nikon d5xxx, DXXXX+/KOOC-0/8-55 or+/KOOC-0/05.

If you usually travel a lot, but are generally interested in photography, you need to record various scenes of your trip. It is suggested to consider a set of Canon xxxd+ 18-200 Nikon d5xxx, dxxx+ 18- 140 or 18-200 (if there is no such matching, you can purchase the matching body and lens separately. Of course, this combination is also suitable for friends who have just learned photography and have limited funds.

For ordinary photographers, Canon Nikon's mid-range camera is the first choice. This level of machine has various professional functions, and the price is relatively cheap, which not only has considerable durability and fuselage strength. You can take all kinds of photos that need special treatment ... >>

Question 3: As a beginner in photography, how to choose SLR camera 1 and budget?

Budget is the first factor in choosing a camera ... because you can't buy anything without money. ...

Seriously, many people don't have a budget when choosing a camera. They went to the store and were told twice that they bought an expensive equipment, but they didn't necessarily buy the equipment that suited them. Store sales will be vigorously promoted because of the high commission of a certain brand, and consumers will often be misled to buy expensive and inappropriate equipment under such promotion means. As a result, an advanced SLR was used twice after being bought home, and then it was put in the cupboard and never used again. So, make a budget for yourself and choose the most suitable equipment in the budget. Budget has little to do with photo quality. Most of us are not billionaires, so it is impossible to buy the best equipment indefinitely, and the best equipment is not necessarily the best for us. Within the budget, do what you can. If the budget is insufficient, consider second-hand or previous-generation equipment.

At present, the upgrading speed of photographic equipment is too fast. As long as a digital camera is properly maintained, it can be used for three to five years or even longer. There is no need to worry that buying the previous generation of equipment will affect the quality of photos. In photography, the fuselage is often worthless, and only high-quality optical lenses can stand the test of time. So, if you choose a interchangeable mirror camera as your camera, I suggest you keep a part of your budget on the lens. Using the previous generation model will make your photos have better quality.

2. Decide your own investment in photography.

When choosing equipment, I often ask them whether to buy a camera to learn photography or take pictures of life. There are many ways to learn photography. Some people will seriously go to the studio to light up and shoot models at high speed. Some people just learn a little fur and share it online, so they enjoy being praised. There may be great differences in equipment selection between two different photographic mentalities.

For ordinary users who take photos of their lives, the card machine and even the iPhone are already the most suitable devices. What they need is a portable automatic exposure photography tool, which can be easily uploaded to the network without a lot of post-production. Recently, Casio's "* * * artifact" is so expensive, only because of the built-in beauty filter. In photographic equipment, such a * * * camera is actually only worth a few thousand dollars, which can be fried to a sky-high price. The big reason is that ordinary consumers will not spend time studying how photography skills can make photos better, but only hope that the equipment in their hands can provide the best photos in the simplest way. This is why we can still find the automatic mode on some high-end equipment.

As for some friends who are interested in learning photography, a camera in manual mode is the most basic requirement. Up to now, more than 98% of my photos are taken in manual mode, but now most advanced digital cameras have four exposure modes of APSM. Semi-automatic and manual exposure modes give the photographer more control over the camera and make it easier to achieve the desired effect.

3. Decide on the subject to shoot.

The subject matter of shooting has a great influence on the choice of equipment. Life photos, street snapshots, landscapes, commodities, portraits, sports, ecology, artistic creation ... Different themes have different requirements for equipment. The most widely used camera for photographing objects is a single mirror reflector. In most cases, SLR can meet the needs of the subject for photographic equipment. However, the size and weight of SLR are not acceptable to everyone. In view of this, the rise of mirrorless cameras has gradually replaced the low-end SLR market in recent years. However, the mirrorless camera is still a new camera type in the market, and the excellent lenses supporting automatic exposure and focusing are still limited. In addition, there is still a big gap between operability and SLR, so SLR is still the mainstream choice for photographers who shoot a wide range of subjects.

For the camera body selection of shooting theme, more consumers just want to take photos of life, travel and snapshots. For this kind of users, I suggest choosing a light camera. Users who have slight requirements for image quality can consider high-end consumer products and m43 systems. Compared with the general SLR, the portable design makes users more interested in using the camera. The higher the camera attendance, the higher the chance of taking good photos.

4, shooting format

The format here refers to the type of camera photosensitive element. There are many kinds of cameras now, which are below 135 frames and are divided into two categories: digital and film. Digital and film are two completely different imaging media, one is photoelectric signal transmission, the other is chemical action, digital is analog signal, linear exposure is nonlinear, adjustable or not, noise is particles, you can check the contrast system ... There is a fundamental difference between them, although it is convenient ... > >

Question 4: How to choose a camera to take pictures in qq? Open mobile QQ, and select the QQ friends you want to talk to. There is a cross icon at the bottom left of the dialog box. Click on it to expand the icon options, and then select the "take a picture" icon to call the camera of the mobile phone to take a picture! Please refer to the attached drawings:

Then you do this:

Menu-Settings-Applications-Find Camera-Defaults-Clear Defaults

When you choose a camera again in the future, an option prompt box will appear. With more and more camera software installed on mobile phones, there will be more and more camera choices. If you plan to use only beauty cameras in the future, check the default settings; Otherwise, an option prompt for choosing a camera will appear every time.

Question 5: How do novices choose cameras? Fuji F85 CCD 2-inch optical zoom 10 times Fuji F505 CCD 2-inch optical zoom 15 times 1500 or so. Don't buy it as long as it is recommended by others, unless you have fully compared it yourself. Some new machines are not fancy and the price is too high. It is better to buy an old model with similar important parameters, which is more cost-effective. The photosensitive chips of portable computers in the market are all 1/2.3 inches, and a few models are11.6 inches11.7 inches, but they are all a little more expensive at each price point, 65438+. There is a Fuji F85 telephoto card machine. The function of the camera is to take pictures, that is, to pursue image quality, so other functions unrelated to image quality are misleading to consumers. To put it mildly, the demand is different. Therefore, it is recommended to buy a large area ccd or cmos. Secondly, select other functions. It is recommended that the camera 1500 (Fuji F85 1500 yuan is preferred, the maximum CCD 1/2, zoom 10 times) Canon IUXS 105 1600 round PowerShot A3000-A. High-definition camera shooting, anti-shake, image quality selection IXUS11500. In terms of image quality, IXUS 1 15HS is much better than Bisogni's. The VGA camera format of Sony W530 and 520 can be basically ignored. The difference between 4-fold dimming and 5-fold dimming is not great in practical use, and the gap at the wide-angle end is more important than that at the telephoto end. Well, I recommend IXUS 1 15HS. If you can buy Sony WX series, it will be better with richer functions and better picture quality. Sony has a two-year warranty, while Canon has only one year. Under 1000 yuan, Panasonic FP 1 700 yuan fp3 1 100 yuan is recommended. As far as brands are concerned, Canon, Nikon, Fuji, Olympus, Casio/Sony and Panasonic all have their own lenses. Others used them later, including Samsung, but Panasonic used the workers' heads of Lycra, Germany. Canon Sony should sell better in home cameras. Sony's industrial design and customs are fashionable, but many people buy them. Fuji's telephoto machine is cost-effective, Olympus's three-proof card and single battery are not bad, Casio's appearance and continuous shooting function are characteristics, and Panasonic's lx series is also good. LX series is the first choice for SLR. Canon's G 12 Nikon P series is also a high-end product in portable cameras, second only to SLR cameras, and the price is between 3500 and 4000. Although close to the cheapest SLR, portability is irreplaceable. Sony's several models are not low in price, and the parameters are not very good. It is better to buy a cost-effective Canon. Let's take a look at the parameter comparison: manufacturer model JD.COM price optical/digital range optical image stabilization electronic image stabilization Canon 2 10 2200 5 times /4 times 24- 120mm Yes1301599 4/4 28-/kloc-0.

Question 6: How to choose a good mobile phone camera and buy a digital camera? Just look at the following article.

1 pixel

The pixel size of a camera usually determines the clarity of photos taken by DC. At present, the mainstream domestic digital cameras have reached 5 million pixels, and many models have been upgraded to 8 million. However, when we usually take pictures, except for the largest pixel, we usually use the size of 3-4 million pixels for large group photos, because this can already take pictures of 3R and 4R very well, and it doesn't take up much space.

2.CCD and lens

CCD is the core part of DC and the photosensitive element of DC. The color reproduction and clarity of CCD photos have a very important influence. The CCD of11.8 is larger than that of 1/2.5. Under the same pixel, the bigger the CCD, the better. Of course, famous brand lenses are better, such as Sony's Chase lens, Canon's lens, Panasonic's Leica lens, Kodak's Schneider lens and Nikon's ED lens. The photos taken by Germans through good lenses are obviously qualitatively different from those taken by other ordinary lenses. Therefore, if the budget allows, we should choose a larger CCD and a better lens.

CCD explanation:

CCD size

When it comes to the size of CCD, it actually refers to the area of photosensitive devices, including CCD and CMOS. The larger the area of photosensitive device, the larger the CCD/CMOS area, the more photons captured, the better the photosensitive performance and the lower the signal-to-noise ratio. CCD/CMOS is an element used for photosensitive imaging in digital cameras, which is equivalent to the film in traditional optical cameras.

The surface of photosensitive elements on CCD has the ability to store charges and is arranged in a matrix. When its surface feels the light, it will reflect the charge to the components, and the signals generated by all the photosensitive components on the whole CCD constitute a complete picture.

If you decompose CCD, you will find that the structure of CCD has three layers, the first layer is "microlens", the second layer is "dichroic filter" and the third layer is "photosensitive layer".

The first layer of "microlens"

We know that the key to digital camera imaging lies in its photosensitive layer. In order to expand the lighting rate of CCD, it is necessary to expand the light receiving area of a single pixel. However, the method of improving the lighting rate is also easy to reduce the image quality. This layer of "microlens" is equivalent to adding a pair of glasses in front of the photosensitive layer. Therefore, the photosensitive area is no longer determined by the opening area of the sensor, but by the surface area of the microlens.

The second layer is a "dichroic filter"

The second layer of CCD is the "dichroic filter". At present, there are two color separation methods, one is RGB primary color separation method, the other is CMYK complementary color separation method. These two methods have their own advantages and disadvantages. First of all, let's understand the concepts of two color separation methods. RGB is a method for separating three primary colors. Almost all the colors that human glasses can recognize can be composed of red, green and blue. The three letters of RGB are red, green and blue respectively, which shows that RGB color separation is formed by adjusting the colors of these three channels. Let's talk about CMYK, which is composed of four channels of colors, namely cyan (C), magenta (M), yellow (Y) and black (K). In the printing industry, CMYK is more suitable, but its adjusted color is not as much as RGB.

The advantage of primary color CCD is sharp image quality and true color, but the disadvantage is noise. Therefore, we can notice that the ISO sensitivity of digital cameras that generally use primary color CCD will not exceed 400. In contrast, complementary color CCD has a Y-yellow color filter, which pays more attention to color resolution, but sacrifices the resolution of some images. On the ISO value, complementary color CCD can tolerate higher sensitivity, which can generally be set above 800.

The third layer: photosensitive layer

The third layer of CCD is the "photosensitive plate", which is mainly responsible for converting the light source of the filtered color layer into an electrical signal and transmitting the signal to the image processing chip to restore the image.

The film size of the traditional camera is 35mm, the diagonal length is 35mm, and the photosensitive area of the 35mm film is 36 x 24mm. When converted into a digital camera, the diagonal length is about 35mm, and the larger the CCD/CMOS size is. In SLR digital cameras, many of them have CCD/CMOS dimensions close to 35mm, such as Nikon D 100, and the CCD/CMOS size area reaches 23.7 x 15.6, which is more than consumer digital ... & gt

Question 7: How do novices choose digital cameras? Preparation steps for buying a camera

Step 1: Make clear the purpose and purpose of buying the camera.

It is very important to determine the purpose and purpose of buying a camera. Only by knowing your own needs can you choose to buy the machine you really need through mergers and acquisitions. Otherwise, you may spend a lot of money on the camera, and it turns out that the functions can't meet your own requirements, or there are too many functions to use at all. We can think about what we buy digital cameras for. For example, some friends buy digital cameras to travel; Some friends want to learn photography; Some friends want to take macro photos; Of course, some people want to take close-ups or take pictures of their newborn children as a souvenir. In short, we must clearly understand consumption.

The output of photos also needs to be considered in advance, whether it is necessary to develop large photos or just watch them on the screen. Through this consideration, we can decide how many pixels are needed to buy a machine. If you just look at it from the screen, then a 3 megapixel machine is enough. If we want to print, and print to more than 10 inch, then we need to buy a camera with pixels as high as possible.

Step 2: Decide the psychological price.

After deciding the purpose and use of buying a camera, you should decide an affordable psychological price according to your own economic ability, such as 3000 ~ 4000 yuan or 6000 ~ 7000 yuan. This can help us save a lot of time and be more purposeful when choosing. DC is still a luxury, so everyone must do his best. There is no point in comparing with others, just enough.

Step 3: Collect information through various channels.

Early data collection is very important, which can give us a certain understanding of the machine to be purchased. There are many ways to collect product information. First of all, many manufacturers will have certain publicity pictorial when they launch digital cameras. We can go to the vendor and have a look. Secondly, media advertising is also a very important way. There are many advertisements for digital cameras in IT newspapers now, so we should pay attention to them. Thirdly, many digital magazines or some newspapers now have a certain space to introduce or evaluate digital cameras, and we can also buy some to read.

If possible, you can download the manual of the corresponding camera and have a look. This is very good for buying a machine: on the one hand, it can make you more familiar with the machine, on the other hand, it can make you ready for basic operation when buying a machine. I like reading instructions myself.

Technical data can let us know the appearance, function and other information of digital cameras. We should look at the actual photos. In this way, you can know the characteristics of DC you are concerned about, such as color, image quality and so on. We can go to the digital photography website to learn about this.

Step 4: roughly determine the model.

The collection of product information is very important, which allows us to fully understand the characteristics of digital cameras. But just looking at these materials, we can only have a perceptual understanding. Only by actually looking at the machine or even trying it out can we have a rational understanding of the machine. This requires us to go to the mall. We can look at the samples in the window or counter. The real machine may look different from the photo, or it may look better. We can also watch others buy machines and listen to what others say. Of course, we can also let the merchants take out the machine, actually touch it and operate it. Depending on the machine, you should also ask the price. When asking about the price, you should pay attention to the fact that the quotation of the merchant usually leaves room for counter-offer. Also, ask them if the price they quoted is licensed or parallel.

Step 5: Choose the right time to buy.

After deciding to buy the machine, we should choose "auspicious day" to buy DC back. Fu's "auspicious day" is actually to seize the opportunity by himself. The price of digital products changes rapidly, so it is very important to judge the market. However, obviously, you should avoid buying before the festival as much as possible. There must be a lot of people buying machines before the holiday, and the price will not be cheap.

Question 8: How to choose a digital camera? What are the precautions? 1. Pay attention to the choice of merchants. The price of the same digital camera (including SLR, non-reflex, portable computer, etc.). ) It's completely different in different stores. Generally speaking, the material market (including a treasure) is cheap, but it is tricky (not all); The price of large online stores is moderate, but it is also tricky (even self-operated); Brand franchise stores (experience stores) are the most expensive but never tricky;

2. Pay attention to the inspection of three yards. It must be checked that the three codes are in one, that is, the fuselage code at the bottom of the fuselage is completely consistent with the serial number on the warranty card (bill) and the serial number on the packaging box;

3. Pay attention to official website registration. Digital cameras sold through formal channels can be registered in the brand official website, and the registration fails or the registered digital cameras have problems;

4. Pay attention to quality inspection. In addition to checking the appearance and appearance of the fuselage, the most important thing is to check the bright spot of the camera LCD and the bad spot of the sensor.

5. Bright spot detection method: Take a pure white and black photo at will, use the zoom button on the fuselage to enlarge the picture, and watch it carefully on the LCD screen (move the cursor up and down, left and right). If there are black spots on the white screen or white spots (including color spots) on the black screen, there are bright spots on the LCD screen, and more than three products will be returned;

6. Bad spot detection method: Take a black photo in RAW format, import it into the computer, and read the photo with the light and shadow magic hand software. There is a CCD bad point detection bar in the software tool menu, and if there is a bad point, it will be returned;

7. In addition, SLR also needs to check the shutter number (Canon EOSMSG software is used for Canon cameras, and Nikon and Pentax can use light and shadow). Digital camera has no mirror lifting system, so it is difficult to crack the engineering mode of the camera (only a few non-inverting micro-sheets have cracked the engineering mode), which can be ignored;

8. Recommended method: Look at the sample and price of a certain treasure first, remember it, then go to the physical store of the treasure (the suggestion of not opening a store is ignored), check according to the process of 2-6 (SLR +7), and pay after checking it is correct, so that you can buy a satisfactory digital camera. If you are greedy and carefree, it is a large online store, and if you have money, it is a brand franchise store.

Question 9: How to choose a digital camera? First, select parameters. According to the price, choose the one with better parameters in the same price.

The most important parameters for choosing a digital camera are:

1, the size of photosensitive element (CCD or CMOS), an important parameter of imaging quality, the bigger the better, the clearer the image. Consumer DC is generally from11.6-1/2.5 inches, and Quan Huafu SLR is 36× 24 mm In low light shooting,

2. The focal length range, at present, the minimum wide-angle end can reach 24mm, and the smaller the shooting range, the wider the shooting range; Looking at the optical zoom magnification at the telephoto end, use the optical zoom magnification × wide-angle focal length = telephoto end focal length, the bigger the foreground, the closer it is. At present, the maximum optical zoom magnification of consumer-grade DC can reach 30 times. Digital zoom is a cloud.

3, the maximum aperture, the greater the low-light shooting effect, the better the background blur. At present, the maximum can reach 1.8, the smaller is generally 3.5, and the smaller the value, the larger the aperture.

4, pixels, picture size parameters. It is worth noting that at present, many people choose cameras to look only at pixels, thinking that the higher the pixels, the clearer the photos they take. In fact, pixels have nothing to do with imaging quality. It is only a parameter of image size. If you want to display large-size advertising paintings and posters, choose high-pixel ones, otherwise you don't have to pursue pixels. Large pixels occupy a lot of storage space, but generally 5-6 million pixels are enough. Too high a pixel is completely meaningless, but it takes up more storage space. In fact, if the card machine with 1200 pixel is set to 6 million pixels, the photos taken are better than those with12 million pixels (it is obvious when the picture is enlarged to 100%).

5, optical anti-shake, which can offset the influence of some jitter and improve the film yield. Digital anti-shake is also a cloud.

……

Second, choose the lens. The lens is also an important part that affects the imaging quality. Famous lens brands include Schneider (used by Kodak), Leica (used by Panasonic) and Zeiss (used by Sony).

Third, choose a brand. The more powerful brands, the order of SLR is Canon, Nikon, Pentax and Sony. Consumer cameras are Canon, Nikon, Kodak, Fuji, Panasonic, Olympus and Sony, in no particular order. These brands can't absolutely say which is better, it depends on the specific products. In addition, don't choose Samsung's camera. Some models of Samsung are attractive only in terms of parameters, but there is still a gap between the actual imaging quality and reliability.

Fourth, choose the shape. There are small card designs and large SLR designs, which are not necessarily good for big images. For example, Panasonic's LX3 card machine imaging is far superior to Fuji S2000HD similar to SLR. However, the optical zoom multiple of general card machines is relatively small, the largest is only a dozen times, while the SLR type can now be more than 30 times.

Fifth, choose a battery. There are special lithium batteries, general AA No.5 batteries, lithium batteries and No.5 batteries. The advantage of lithium battery is small size and light weight, but the disadvantage is that it can't be bought anywhere, so it must be recharged and expensive. The advantage of AA battery is that it can be obtained everywhere and has high cost performance. Disadvantages are large size and heavy weight, and high-quality batteries must be selected. This is very important. Many people think that AA batteries have poor endurance. In fact, it is mainly the quality of the battery. The endurance of high-quality AA rechargeable batteries is very good, and the cost performance is far superior to that of special lithium batteries. At present, the best No.5 Ni-MH battery only has eneloop from Sanyo, Japan and enelong from China, and the performance is basically the same, but the capacity of Aifu is a little larger, and the price is also very cheap, which is a little more than 6 yuan, twice as expensive as that in Japan! Other batteries are not easy to use, especially those with a nominal capacity of more than 2500mAh, including Sanyo and Tang Qian, which are all floating clouds. Ordinary AA dry batteries can only be used for emergencies, but also genuine brand-name batteries, otherwise the machine may not start.
