What does camera format mean?

Question 1: What does full-frame and non-full-frame mean in a camera and what is the difference? This refers to the size of the sensor, the larger the sensor size the better the image quality of the camera, the camera is also the more upscale price is also more expensive

The full-frame sensor length and width dimensions of the sensor is about 36x24mm, and the traditional 135 film negatives are as large as the sensor is more advanced at present, mainly for the use of high-end DSLRs

As long as the size of the sensor is smaller than the full-frame can be

As long as the size is smaller than the full-frame sensor can be Called non-full-frame sensor, mainly refers to the entry and mid-range SLR with APS-C format sensor, length and width dimensions of about 24x16mm (different manufacturers of the sensor size is slightly different)

There are also smaller sizes such as the M4/3 sensors, with the length of the diagonal, such as 1.5-inch sensors, 1-inch sensors, 1/1.7-inch sensors, 1/2.3-inch sensors and so on can be collectively referred to as the Sensors such as 1/1.7-inch sensors, 1/2.3-inch sensors, etc. can also be collectively referred to as non-full-frame sensors

Question 2: What is the meaning of full-frame and aps-frame for DSLR cameras? The sensor in a digital camera is called a CCD or CMOS.

It is the equivalent of the film in the original film cameras.

The original 135 film camera had a negative size of 36mmX24mm.

Full frame means that the size of the CCD (CMOS) in a digital camera is basically the same as the size of the original negative, which is also 36mmX24mm, and is therefore called full frame.

The original meaning of APS is "Advanced Photo System".

It was a transitional product before the popularization of digital cameras.

It still used film, but recorded a lot of relevant data on the film and cartridges through magnetic materials and digital programs.

One other feature is that the APS allows the user to switch between three format formats at any time. They are:

H-format, 30.3×16.6mm, with an aspect ratio of 16:9;

C-format, 24.9×16.6mm), with an aspect ratio of 3:2; and

P-format, 30.3×10.1mm, with an aspect ratio of 3:1.

The APS-C format is only that of a digital camera with a CCD (CMOS) of the Size is similar to the size of APS's C-format, about 25mmX17mm. It is almost half the area of a full-frame CCD (CMOS), also known as a half-frame camera.

Because of the reduced area of the CCD (CMOS), reducing the cost, the digital SLR has been popularized. Valve to date the price difference between the cheapest full-frame and the cheapest half-frame camera is almost five times or so.

Most DSLRs are APS-C format.

But the sizes are similar but small.

Nikon's is the largest, with a full-frame scale factor of X1.5;

Canon's is slightly smaller, with a full-frame scale factor of X1.6; and

Sigma's is the smallest, with a full-frame scale factor of X1.7.

In fact, Canon has another APS-H digital camera, the EOS-1D (not the 1Ds) series.

In fact, Canon also has an APS-H digital camera, the EOS-1D (not 1Ds) series, which has a full-frame scale factor of X1.3.

Question 3: Difference between DSLR frames DSLRs are generally divided into four frames, aps-c aps-p, full-frame, and large-format

The standard here is that the size of the film inside the former film camera prevails, and the same size as film is known as full frame, and bigger than the film becomes the large format. The 1/1.6 is called aps-c and the 1/1.3 is called aps-p.

Generally, in the home aps-c, like 700d, d5200, d7200, 80d, etc., and full-frame, like 5diii, d810, etc., and the large-format, like the Lexmark Hasselblad Mamiya, are expensive cameras, basically.

Question 4: What does full-frame mean on a DSLR? To put it simply,

with a non-full frame camera, the picture you actually take is smaller than the image you see in the viewfinder!

And with a full-frame camera, the size of the picture you take is the same as what you see in the viewfinder.

You can get a non-full frame camera to take a picture and try comparing it,.

Question 5: The difference between a full-frame camera and a medium format camera First of all, you need to understand what is called absolute depth of field, what is called relative depth of field

We take the interchangeable lenses of the APS and full-frame as an example, it will be easier to understand

The APS sensor is small, which will cause the lens focal length of the full-frame lens multiplied by 1.5, which is the relative depth of field is smaller, in fact, the depth of field is The depth of field is actually unchanged. You can refer to the New York Institute of Photography textbook on focusing. When we talk about focus accuracy and depth of field, we are referring to the "area that looks sharp". For example, if you look at an advertisement, you will see that it looks sharp from a distance, but if you look closer you will see that there is still a slight difference in depth of field, and if you look further in, you will see that it is very blurry. The small sensor for the focal length of the amplification effect, just equivalent to the same picture to pull you closer, the depth of field feeling standard is determined by the size of the picture, the smaller the picture (pulled close to the equivalent of a part of the original picture from the interception of the standard depth of field, you feel the depth of field of the compressed

What is called the absolute depth of field? Let's say, you first shoot with a fixed focal length head in full frame, use a ruler to measure the depth of field, clear focus to a certain line, you take the thickness of the line as a standard, obviously the line before and after this line will be blurred. Assuming you consider a line blurred and diffused to be "sharp" if the halo is no more than three times the thickness of the line itself, you can get a depth of field range based on the scale of the ruler. If you change the APS camera, the lens aperture remains unchanged, wow is the above method to get a depth of field range, although it looks blurred, in fact, the two depth of field range is the same

About perspective, this issue is also very simple. We all know that short focal lengths have pincushion distortion, but have you ever noticed that the pincushion distortion spreads from the center and gets worse the further you get to the edges. You use a full-frame + 100mm lens imaging size is 36 * 24mm, medium format imaging to be larger than this size, but medium format in the middle of the 36 * 24mm of the piece, that is, pincushion distortion is very small piece of the piece, but also and full-frame plus the lens imaging the same piece. That is to say, the perspective of 100mm on medium format is mainly in the area beyond 36*24. You can compare the two cameras when you have a chance

Question 6: What is the distinction between full-frame and half-frame DSLRs? And what does Canon's EOS mean? Hello,

The full-frame and half-frame DSLR cameras generally look at the size of the CMOS, the so-called full-frame is for the size of the traditional 135 film. Previously, most of the digital SLR CCD size is smaller than the size of 135 film, and full-frame digital SLR CCD (or CMOS light-sensitive imaging element) size and 135 film size is the same. And the larger the CCD size, the higher the image quality. Full-frame CMOS / CCD size is 36 x 24mm, while the size of the half-frame is 24.9 × 16.6mm, relative to the full-frame, to be much smaller, this is the difference,

Now the general machine front are marked Oh, such as Nikon's D600 and D5200, the box are labeled, the D600 is the FX format, the D5200 is the APS-C format! (half-frame machine) Canon is the same

Canon's EOS is a code name, the full name is Electro Optical System (Electro Optical System) - EOS, Canon would like to say that the Canon EOS series of cameras is a high-precision machine. So the name EOS,

I hope to help you, I wish you a happy life

Question 7: What is the meaning of half-frame and full-frame in the camera There is no concept of half-frame, only APS-C format, and full-frame

Full-frame is the same size as the 135 film sensor, APS-C format is generally about 24 × 16MM sensor, different manufacturers of APS format cameras, and the same size of the sensor, APS-C format is generally 24 × 16MM sensor. APS format cameras from different manufacturers have slightly different specifications.

The two comparative full-frame sensors are a bit larger, and in the same focal length lens configuration, you can get more range of view, more convenient.

There is also a medium format, that is used in high-end cameras, the sensory element and film medium format film the same size

Question 8: What is the difference between SLR full-frame and non-full-frame cameras? The so-called full-frame is for the size of traditional 135 film. Most of the previous digital SLR CCD size is smaller than the size of 135 film, while the full-frame digital SLR CCD (or CMOS light-sensitive imaging elements) size and 135 film size is the same. And the larger the CCD size, the higher the image quality. And for those who already have a traditional DSLR, there will be no conversion issues with lens use. Non-full-frame cameras, such as the Canon EOS 400D, 50D CCD size is probably equal to the film size of about 2/3, 100mm lens, after conversion 1.6 magnification will become a 160mm lens. At the wide-angle end of the 24mm, full-frame is more advantageous, the visual is very wide, and used in full-frame is very embarrassing, X1.6 Equivalent to 38mm.

The traditional camera film size of 35mm, 35mm for the width of the film (including the perforated portion), the 35mm film's light-sensitive area of 36 x 24mm. converted to a digital camera, the diagonal length of the diagonal length of the camera about nearly 35mm, the larger the CCD/CMOS size. In DSLR digital cameras, many have CCD/CMOS sizes close to 35mm, such as Nikon's D100, which has a CCD/CMOS size area of 23.7 x 15.6, which is much larger than consumer-grade digital cameras, and Canon's EOS-1Ds, which has a CMOS size of 36 x 24mm, which is up to 35mm, and so has relatively good imaging. We'll call them full-frame.

Question 9: What do you mean by half-frame camera Those who want to buy a DSLR must have seen the discussion of full-frame and half-frame, so what exactly do full-frame and half-frame refer to?

We know that the current digital SLR cameras, from the optical principle and the traditional film SLR is still the same, just the original light-sensitive part of the film replaced by an electronic sensor CMOS or CCD.

Full-frame and half-frame refers to the size of the electronic sensor (CMOS / CCD).

The size of the electronic sensor in full frame is as big as traditional 135 film, which is 24×36mm.

The size of the half frame is about 23.7×15.6mm, or what is called the APS-C format.

On the face of it, the two are just different sensor sizes, and for our average consumer, what is the specific difference between full frame and half frame?

1. price, half-frame has a clear advantage;

2. size and weight, half-frame is more lightweight, there is also a clear advantage;

3. lens group, the two each with a different lens group, can not talk about which one is more advantageous, if you have to say that the advantage, I think it is still half-frame slightly advantageous, because half-frame body half-frame lenses full-frame lenses can be used, while the full-frame

4. Depth of field, the depth of field of the full-frame camera is more shallow. Since we usually need both a large depth of field and a shallow depth of field, it's hard to say which is better or worse at this point;

5. In terms of image quality, full frame has a certain advantage. Specifically look at this advantage, the first is the advantage of large print details, which is not very meaningful to most ordinary consumers, because we usually rarely print more than 30 inches of photos to look at, and print ordinary photos or look at the computer, it is difficult to see the difference between the two. Secondly, it is a better high-sensitivity image quality. High-sensitivity in some special scenes is very helpful to take clear photos, such as shooting theater performances, wedding stage, etc., as well as shooting sports, such as basketball, car racing and so on. If we are not professional sports photographers, and if we are not relying on wedding photography or stage photography for food, then most of the photos of usual travel, parties, portraits, etc. are still taken with low sensitivity.

There is nothing wrong with the pursuit of "faster, better, higher". If there is no cost to achieve such a goal, of course we will not refuse; if you have to pay a considerable price, you need to make the right trade-offs. If you don't spend money on something, everyone will take it for free. If you want to spend money on something, you need to think about it, and common sense applies to the topic at hand.

Conclusion: Unless you have an urgent need for high image quality and are willing to pay a high price for it, a half-frame camera is enough for the average consumer.

Some people read a lot of information and may ask, although full frame is expensive, but isn't full frame the direction of the mainstream in the future?

I would like to say that the mainstream direction in the future will not be full frame, but miniaturized cameras.

Overall, the process of camera development is also a process of miniaturization, and the now widely used 135 system is a product of the revolution of the larger 120 system. Just look at the "better" equipment in your hands, and it's easy to see that the road to miniaturization is still a long way to go. As far as film systems are concerned, they are also making efforts to miniaturize, and the APS is the result of these efforts. If not for the impact of the digital tide, APS may have formed a certain climate today.

The trajectory of digital systems seems to be the opposite, starting from a small size and then working towards a larger size, and in the eyes of many, "full frame" seems to be the ultimate goal in recent times. This seems to be contrary to the pursuit of miniaturization, but it is not difficult to understand: the initial technical limitations, CCD is too small, many indicators can not meet the basic needs, CCD large-scale will naturally become the first task of this period. With the continuous development of electronic sensor and chip technology, the picture quality of half-frame cameras has become increasingly close to, or even beyond, the needs of ordinary consumers, and the continued development of full-frame, like the blind pursuit of high pixel, is simply a pandering to the market misunderstanding.

In 2007, Nikon launched its top full-frame camera, the D3, and when we saw the wedding samples taken by the D3, we all sighed in unison: the original ISO3200 is also available! Many of my friends have also developed a worshipful and even obsessive attitude towards full-frame image quality. But only three years later, in 2010, Nikon launched a half-frame camera D7000 high-sensitivity image quality has been close to the D3, and low-sensitivity image quality is beyond the D3. The rapid development of technology continues to impact on the world of our thinking in the bars and boxes, everyone ...... >>

Question 10: What is the meaning of the digital camera APS format APS-C is the abbreviation of Advanced Photo System type-C (APS-C).

This is one of the specifications for the image sensor used in a digital camera. The dimensions are slightly equivalent to those of the Advanced Photo System type-C, at 25.1mm x 16.7mm, with a ratio of 3:2.

This type of sensor is commonly used in many DSLRs, but also in some consumer digital cameras, such as the DSLR DSC-R1, the Sigma DP1, and the Fujifilm X100.

Some DSLRs also use this specification, such as the Sony NEX-5/3 and Samsung NX10.
