Canon official information, very good SLR camera introduction information, whether you are a novice or not, it is strongly recommended to read it carefully.

Introduction to SLR Camera Nikon never said that Nikon digital SLR has only two formats, FX Quan Huafu and DX non-Quan Huafu. The main difference between the two is the introductory course of SLR cameras.

Introduction of SLR camera The size of the image sensor CCD or CMOS of FX format camera is 24*36mm, and the size of the photosensitive chip is the same as that of the traditional 135 film camera. When a full-frame camera uses a lens, the focal length can be exactly the same as the original lens, and there is no need to convert the magnification. Introduction course of SLR camera

The image sensor in DX format has a slightly smaller photosensitive area than the traditional 135 film camera, so it is equivalent to enlarging the central part of 135 film, so it is equivalent to the traditional 135 SLR focal length by multiplying the conversion ratio of10.5.

For example.

The lens with 50MM F 1.8 is 50MM on FX model and 50* 1.5=75MM on DX. That's why non-full-frame cameras use 50 mm fixed focus to shoot portraits, while Quan Huafu uses 85 mm fixed focus. The larger the focal length, the better the blur of the same aperture background. This is the real reason why the whole background is blurred better, not telling the second floor ~

Introduction to SLR cameras Full-frame cameras have better imaging quality because of the large photosensitive chip area. Moreover, at present, full-frame cameras are professional machines, with relatively high prices, good operating feel and excellent materials and workmanship.

DX format is enough for the introduction course of SLR cameras. You are not going to burn money or change Quan Huafu in the future. Also, remind you that the price of the lens of the entry machine should not be half the price of the first camera, otherwise the film will be bad. The biggest impact of SLR imaging is not the camera, but the lens. Of course, to quote a sentence from the infinite forum, the most important thing in photography is the head behind the lens. Study hard and enrich yourself is the most important thing, isn't it?
