Canon switched lens mounts on me so I had to start all over anyway. Although I never really gave up shooting with canon. I still shoot with 1Dmk3s, 7Ds, and 5Dmk2s...shhh nobody here is suppose to know though!
Ooh! A DSX1000! Nice solid camera!
It's kind of solid, but not really. It's certainly not FM2 solid. My uncle's basement is very humid, the original leather case rotted to hell (but I still like the Mamiya logo on it!) and the self timer button crumbled. The film advance lever is a bit chintzy- but everything works. The shutter speed dial doesn't have that same "klunk" when you turn it, like the FM2. But it's a great camera, has a nice lens. The mount is plastic too, if I remember right. I think I have a 55mm 1.4 on it.
