Dude....you and your darned thread....you have now changed some of my trajectory! lol I looked at another one of my bear photos and I have always wanted to shoot with a Mamiya system and started googling around and the Mamiya M645 1000s looks like a great creative tool and I could probably be out the door for under $600.
I think I would love to shoot some urban stuff and creative portraits with this stuff. Did you use The Darkroom for your processing? It looks relatively inexpensive to just get the negs developed and then I could scan (with my own scanner) as wanted and needed.
I sorta like the idea of NO IMMEDIATE GRATIFICATION and what a great way to kill the "chimping" habit! I would probably shoot both digital and analog on a shoot just to have the ability to verify my composition.
