One of the things about Mamiya TLR's that doesn't get mentioned much is their ability to be fine tuned. Without messing around with the optics, you can adjust the distance between the ground glass and the focal plane, and also the angle of the mirror to arrive at the quintessential optimum clarity. I have two TLR bodies and dedicate one for my 55mm and 80mm lenses and the other for my 180 super, with each body tuned differently for their given lenses.
Here's another bonus; loading film while the camera is on the tripod. And still another, bellows focusing which enables extreme close ups with all but the telephoto lenses.

I'll never need or want any other medium format camera. I have flirted with the Rollei SL66, but I the C220 has given me everything I have ever asked from it.
