SLR camera lens area distinction
4. kit is the dog head, digital SLR if you want to take pictures, must be the body plus lens Caixing, it must buy a lens, even if the dog head.
5. If you just get started, you can buy a dog head to practice (f3.5-5.6), and then consider a little better lens (4K above the lens)
6. The diameter of the lens is often easy to be ignored, but the diameter is better (52mm and 77mm)
3. Model to see their affordability, entry-level SLR sensors are similar. Do not have to care about, if the money can buy a full frame of the SLR (sensor size, and the bigger the better), to more than 10,000, a little expensive
1. D80 do not buy, very old models!
2. buy only one copy of the Japanese brand, Canon and Nikon. Do not think about the other.
8. Clear at night the general need to shoot people flash, shooting still life can be used for a long time exposure. All the cameras have three basic parameters: shutter, aperture and exposure, adjust the parameters of the ultimate goal is to ensure the appropriate exposure, the faster the shutter, open the time is short, less light into the sensor, so the shutter is too fast Easy to lead to underexposure, the aperture has two purposes, mainly to control the same aperture, the larger the caliber (f value is smaller) the same time to enter the sensor more light, but the larger the caliber, the more shallow the background, By controlling the depth of field (relatively small depth of field) to achieve, the higher the exposure, the more sensitive sensors, less light into the normal exposure, but the exposure is too high and easy to noise. Entry-level SLR is generally recommended not to be greater than ISO400. (Canon can go to ISO800)
9. other people answered too much, I will not repeat. Hope it helps you.
There is the size of the sensor area is the camera body parameters, and the lens has nothing to do, the larger the sensor area, the unit area of ??the pixels on the more, if the same pixel, the larger the area, then the larger the area of ??a single pixel, The effect is better and more real.
7. Virtual background requires a large aperture (f1.4 or f1.8), the standard lens 50mm fixed focus lens shot portrait is good, cheap head less than 1000 dollars. But the need to shoot the smallest focal length of 18mm lens, sometimes still have to use.
