Does commercial photography have to be full?

Excuse me, are you talking about personal photography, such as Taobao shop photography, or are you going to engage in this industry, such as photo studio and contract photographer?

If it is the former, half a picture is enough;

If it is the latter, don't consider it, the full-frame SLR is standard! Even if you can't go to 5D3 and 6D, you can still consider it. Not only is the monomer larger than the full-width photosensitive element now, but also a larger visual range and better texture can be obtained under the lens configuration with the same focal length. Moreover, many demanding photographic requirements can only be met by machines in Quan Huafu, such as 1 sec 14 picture, which requires half a picture, and so on.

I'll show you the same focal length, the size of the full picture and the size of the half picture.
