Having processed thousands of rolls for many photographers in sydney I know of quite a few who have used Bronica for certain shoots at certain times in their career....
here are some links to works by some of those guys and gals I can recall off hand having at some point used this camera....

I could go on and on with links but my point is loads of professionals used Bronica.
