I just counted over 50. There are some that I can't find right now. I think that I will inventory them this weekend.
I don't know bout other photogrphers but people just give them to me.
Believe it or not,each one has its one personality.
I use a Canon EOS 630 most of the time.I also enjoy an old Rolliflex and a Mamiya 645 1000. with a left hand grip.
So many cameras so little time!
