Do you really know the difference between a SLR camera and a digital camera?

For photography enthusiasts, a high-profile SLR camera is essential, so why do you choose a SLR camera? Is there a digital difference between a SLR camera and an ordinary digital camera? Some people may choose SLR cameras purely because of fashion or follow suit. In fact, SLR cameras do have their own advantages, which are not available in ordinary digital cameras.

The landlord is also a photography enthusiast, saves a lot of money to buy a SLR, or a factory directly from the Klip Mall to buy products directly, the price is very cheap, and the key is the quality is quite reliable, the factory direct supply does not say anything. As a veteran photographic equipment enthusiast, the following landlord will come to the difference between some SLR cameras and digital cameras for some white children's shoes:

Different structure

SLR digital cameras are two products that are totally different from our ordinary digital cameras. The difference here is mainly reflected in the internal structure of the two. It is the same as the traditional SLR camera. The digital SLR camera is basically the same. Solved the problem of aberrations, that is to say, from the inside of the viewfinder is the image that will be exposed on the film. The ordinary digital camera adopts the CCD photosensitive mode, and everyone sees the image that the CCD feels on the LCD. That is to say, the photographer sees the image that everyone will shoot on the LCD screen, and there is no problem with the difference, so the ordinary digital camera can also shoot the macro! So from this point of view, the SLR camera is not dominant.

Shutter problem

Ordinary digital cameras are enough for ordinary users to take photos of this tour, but its shutter speed is extremely important for photographers who have higher requirements to adapt to harsh shooting conditions, the fastest in ordinary digital cameras. The shutter speed is extremely important to maintain around 1/1000 seconds, and the fastest shutter speed of a SLR digital camera can easily reach 1/10000 seconds. Such a fast shutter speed makes the ordinary digital camera far behind, and is very suitable for shooting ecological environment.

Different lens

SLR digital cameras not only support a large number of matching lenses, but more importantly, there are also heights that cannot be achieved by ordinary digital cameras. First of all, like the wide-angle end shooting effect, most ordinary digital cameras stick to the 35mm ~ 38mm position, a few high-end models support the 28mm wide angle, but the SLR digital camera usually uses the original lens to take a comfortable wide-angle landscape photo With the special wide-angle lens, you can even continue to expand the visual range. Secondly, the digital camera is very sensitive to jitter. Even slight shaking during the exposure process will produce blurred photos. If the ordinary digital camera is not a high-power zoom lens model, many of them do not have the practical function of anti-shake, and the SLR digital The camera can also be equipped with a lens to prevent the unstable jitter in the shooting.

In addition, the lens part is closely related to the imaging quality. Comparing the lens of most ordinary digital cameras and SLR digital cameras, we can see that the lenses of ordinary digital camera lenses are small and disproportionate to the lens barrel diameter. Some models have only mirrors. The diameter of the cylinder is about 1/3, and the lens of the SLR digital camera lens is basically the same as the lens barrel diameter, which also causes a huge difference in the optical performance of the two systems. In short, the choice of one lens is more than one point of shooting protection, a good lens can make the shooting work freely.

Area difference of photosensitive material

Most digital SLR cameras use 2/3 of the full-frame size as the photographic material, and a few high-end products have the full size (that is, the same size as 35mm film), which is often several times larger than the ccd used by ordinary digital cameras. Therefore, the digital SLR is generally very small, and the control of the ordinary digital camera is much worse. For example, the 800w canon 20D and the 800w sony f828 are much different than the defect control.

The above are the most important differences between SLR cameras and digital cameras. Do you know all the friends?
