What is the difference between a DSLR and a regular camera?

The full name of the SLR is single lens reflex, SLR camera in the view and shooting with the same lens, dual-lens reflex camera and SLR camera is almost the same, dual-lens a lens used for shooting, another lens used for the view. A DSLR camera is a camera that uses a single-lens reflex to obtain an image for observation and shooting. The viewfinder of a DSLR camera is called a TTL (Through The Lens) SLR viewfinder. This is a must-have viewfinder for professional cameras, and it is an optical viewfinder that passes through the lens without error. This type of viewfinder has a range of up to 95% of the actual image. The only drawback is that if the lens is too small, the viewfinder will be very dark, affecting manual focus. Fortunately, nowadays, they are equipped with autofocus, which is no longer a problem. Of course, if you use a TTL SLR viewfinder, in order not to make the viewfinder too dark, the manufacturer will use a large caliber advanced lens, so the current SLR camera lenses are generally larger, is the result of this factor.

Difference between SLR digital cameras and ordinary digital cameras

1, the structure is different

SLR digital cameras and we have more contact with the ordinary consumer digital cameras are completely different from the two systems, the difference is mainly reflected in the internal structure of the two, and the same as the traditional SLR cameras using a special construction, digital SLR cameras fundamentally solve the problem of the aberration, that is to say, from the viewfinder to the viewfinder to the viewfinder, the viewfinder is not the same, but the viewfinder is not the same. Problems, that is to say, from the viewfinder to see the inside is to be exposed to light on the film image, ordinary digital cameras due to the use of CCD light-sensitive mode, we see on the LCD is the CCD feel the image, that is to say, the shooter in the LCD screen to see is also the image we will shoot, there is no aberration problem, so ordinary digital cameras can also shoot good macro! So from that point of view, DSLRs don't have the advantage.

2, the shutter problem

Ordinary digital cameras for ordinary users to shoot photos of this trip has been enough, but its shutter speed to have higher requirements to adapt to the harsh shooting environment of the photographer is extremely important, the fastest shutter speed is extremely important to maintain the fastest shutter speed in the ordinary digital cameras in 1/1000 seconds, and the fastest shutter speed of the DSLR digital camera! The fastest shutter speed of a DSLR camera can easily reach 1/10,000 seconds, which is too fast for a normal digital camera and is ideal for shooting ecological environments.

3, the lens is different

Mention of DSLR digital cameras many people will enjoy it has a variety of lenses can be supported, some people believe that the biggest difference between DSLR digital cameras and ordinary digital cameras is that one can replace the lens of the other can not be, at first glance seems to be very reasonable, think about it in fact is not. For example, the Olympus E20P is a DSLR camera with non-interchangeable lenses, but of course most DSLR cameras on the market have supporting lenses behind them. You can change lenses for different special effects during a shooting session, look through the viewfinder to see the different special effects, and then choose the right lens to try to shoot with.

The DSLR not only has more supporting lenses, but more importantly, the lens metrics of the DSLR also have a high degree of performance that ordinary digital cameras can't achieve. First of all, such as the wide-angle end of the shooting effect, most of the ordinary digital cameras adhere to the 35mm ~ 38mm position, a few high-end models of the lens support to 28mm wide-angle, but the DSLR digital camera is usually the use of the original lens can be shot out of the comfort of the wide-angle landscape photographs, with a special wide-angle lens or even continue to expand the range of visibility. Secondly, digital cameras are very sensitive to shaking, even if the slightest shake in the exposure process will produce blurred photos, if the ordinary digital camera is not a high zoom lens model, many do not come with anti-shake this practical function, while the SLR digital camera can be added to the lens to prevent the shooting of unsteady holding the camera shaking occurs.

In addition, the lens part of the imaging quality is also closely related to the comparison of most of the ordinary digital cameras and SLR digital camera lenses, we can see that the ordinary digital camera lens lens lens is very small, and the barrel caliber is not proportional to some models of the lens is only the barrel caliber of the 1/3 or so, and SLR digital camera lens lens lens is basically the same caliber as the barrel, which has caused a huge difference in the optical performance of the two systems. This also results in a huge difference in the optical performance of the two systems. In short, one more lens choice is one more point of protection when shooting, and a good lens can make the shooting work from the comfort of the completion.

4, the difference in the area of light-sensitive materials

Digital SLR cameras most of the full-frame 2/3 for the light-sensitive materials, a few high-end products to achieve a full-frame (that is, the same size as the 35mm film), often several times larger than the area of the ordinary digital camera ccd, so the digital SLR is generally a very small manic point, while the ordinary digital camera manic control to be poor, a lot, for example, 800w canon camera, the canon camera, the canon camera is a good example of a good lens can make shooting work done with ease. For example, the 800w canon 20D and the 800w sony f828 have a huge difference in the control of the ccd, so it's impossible to compare!

Highlights

1, digital SLR cameras and traditional SLR camera shutter is a high failure rate of components, because the first in the shooting time is the reflector to turn up, and then storm, this series of action is very fast, and are mechanical devices. Some friends in the use of SLR may have noticed, when the shutter is pressed a moment, look out from the viewfinder, only see a black, through the above explanation you should know why, after pressing the shutter reflector will be turned upward so that the light can be reached through the lens to the CCD or CMOS for exposure (the reflector is equivalent to a switch of the light path).

2, SLR cameras in the replacement of the lens is very easy to enter the internal gray, especially digital SLR, if the CCD is dirty above the general need to get a professional maintenance department to clean (free of charge within the warranty period, over the warranty period, it seems to be a few hundred sheep, expensive)! So when replacing the lens try to find a clean and dust-free place to carry out.

3, many just use SLR digital camera users complain that the SLR digital camera photos gray color, sharpness is not enough, and even less than a pocket digital camera as bright. In fact, this is not a problem of the camera. This is because the picture processing concept of DSLR is totally different from that of pocket digital camera, the image information recorded by DSLR is more abundant and real (more original data is retained) so that users can have a greater range of adjustment to get more satisfactory pictures, and at the same time, it also requires users to have a certain level of computerized photo processing. Pocket-sized digital camera will be in the picture processing automatically, such as color exaggeration and image edge sharpening, etc., leaving very few conditions for the user to post-processing.
