The focal length of 1 and 16-50 lenses is 16mm at the wide-angle end and 50mm at the telephoto end.

2. 6400 itself is in C format, so how can it be used in Quan Huafu? With all due respect, you haven't understood the true meaning of C-frame and Quan Huafu;

3. Shoot 50 people and you can shoot 100 people. The key is that the size of your venue allows. Simply put, the camera should have enough distance from the crowd, but unless it is in the square, in most places, this is impossible. Camera back to a certain distance, no way back. There are buildings behind, but people still can't take pictures;

Your lens is a zoom lens, and the wide-angle shooting angle is very large. As long as the venue allows, it is no problem to shoot 50 people. But you, you have to know that wide-angle portraits will be deformed;

5. Why do you want to ask a professional photography agency to take a group photo of a large conference instead of using an ordinary SLR? It is because ordinary SLR takes a lot of people, and the wide-angle lens will be deformed, that is, the people taken are unreal and overweight.
