The 6x7 is noisy, but has less mirror or shutter induced vibration than a Super program. The earliest model didn't have MLU, but all models made in about the last 20 years have it. > > Any recommendations regarding finders?

The prisms all cut off quite a bit, I think almost 15% of the finder is cropped on the 6x7. I don't know about the new version. Something to keep in mind. Unfortunately, the prism finders are the only way to get a properly oriented viewfinder image The waist level finder is nice, but the camera is odd to use with it, as is the chimney finder. > > How about lenses?

You can approximately double the 35mm focal length number to get a lens focal length whose field of view approximates the 6x7. About the only 6x7 lenses to be leary of are the old Takumar 75mm f/4.5, which has some flare problems, but is wonderfullt sharp, and the Takumar 200mm f/4, which is not as sharp as the later SMC Pentax 6x7 optic.
