Different structure
SLR digital cameras and we are more in contact with the ordinary consumer digital cameras are completely different from the two systems, here the difference is mainly reflected in the internal structure of the two, and traditional SLR cameras like the use of a special structure, digital SLR cameras fundamentally solve the problem of image aberration.
It means that what you see inside the viewfinder is the image that is going to be burst on the film, ordinary digital cameras due to the use of CCD light-sensitive mode, what you see on the LCD is the image felt by the CCD, which means that the shooter sees on the LCD screen is also the image that you will shoot, there is no aberration problem, so ordinary digital cameras can shoot good macro! From this point of view, SLR cameras do not have the advantage.
Shutter problem
Ordinary digital cameras are sufficient for ordinary users to take ordinary photos, but its shutter speed is extremely important for photographers who have high requirements to adapt to the harsh shooting environment, the fastest shutter speed in ordinary digital cameras is extremely important to maintain at about 1/1000 seconds, while the fastest shutter speed of SLR digital cameras can easily reach about 1/10000 seconds, so fast Shutter speed so fast that ordinary digital cameras are out of reach, ideal for shooting ecological environment.
Different lenses
When it comes to SLR digital cameras, many people will be happy to say that it has a variety of lenses that can be supported, and some people think that the biggest difference between SLR digital cameras and ordinary digital cameras is that an interchangeable lens and another can not, so it seems to make sense, when you think about it, it is not.
For example, Olympus E20P is a non-interchangeable lens SLR digital camera, of course, the majority of SLR digital cameras on the market behind the support of the lens group. In the shooting activities we can change different special effects lens, through the viewfinder will be able to view the different special effects, and finally choose the right lens to try to shoot.
SLR digital cameras not only support more supporting lenses, more importantly, in the lens indicators also have ordinary digital cameras can not reach the height. First of all, such as wide-angle end of the shooting effect, most ordinary digital cameras adhere to the 35mm to 38mm position, a few high-end models of lens support to 28mm wide-angle, but SLR digital cameras can usually use the original lens to shoot a gratifying wide-angle landscape photos, with a special wide-angle lens can even continue to expand the visual range.
Secondly, digital cameras are very sensitive to shake, even slight shaking in the exposure process will produce blurred photos, if ordinary digital cameras are not high zoom lens models, many do not carry the practical function of anti-shake, while DSLR digital cameras can be added to the lens to prevent the occurrence of unstable shaking in the shooting.
In addition, the lens part and imaging quality is also closely related to the comparison of most ordinary digital cameras and SLR digital camera lens we can see that the lens of ordinary digital camera lens is very small, disproportionate to the caliber of the lens barrel, some models of the lens is only about 1/3 of the caliber of the lens barrel, while the lens of SLR digital camera lens is basically the same as the caliber of the lens barrel, which also caused the two systems optical performance of the performance of Huge differences in the optical performance of the two systems. In short, one more lens choice is one more point of protection when shooting, a good lens can make the work of shooting from a comfortable and comfortable to complete.
The area of the light-sensitive material difference
Most digital SLR cameras use the full width of 2 / 3 for the light-sensitive material, a few high-end products to the full width (is the same size as 35 mm film), often several times larger than the area of ordinary digital cameras using ccd, so digital SLR general mania point is very small, and ordinary digital cameras mania point control is much worse, for example, 800w canon 20D and 800w For example, 800w canon 20D and 800w sony f828 than the mania point control is too big a difference.
