When I purchased it, I was torn btwn the Contax, and the Mamiya. I like the "warmer" glass of the Mamiya. The Bronica I feel is a little cooler. Grerman optics and all. That is also why I did not go hassy. I have been satisfied with the Mamiya, but I am getting a bit disgruntled now. Grumble Grumble.
I have had Hassy, Bronica, and Mamiya. I still go back to the Mamiya everytime. It just "feels" good! :-)
