What kind of SLR camera does the studio photographer use?

SLR is professional, and entry-level is also professional. If you want to develop, I suggest going to Quan Huafu for SLR. If the funds are limited, it is almost 1 10,000. Canon and Nikon have their own advantages and can choose according to their own usage habits. Pentax doesn't make mistakes. After all, there is no essential difference between machines of the same grade in the SLR camp.
