Any users here?
I plan to get the TS adapter for mamiya lenses.
What is the equivalent field of view for 80mm, and 55mm lens?
Thanks

Hallo Prashant,

The focal length is the focal length is the focal length. An 80mm 645 lens will behave as an 80mm lens on a 35mm.

When shooting any 645 format focal length, multiply it by about 0.577 for the 35mm equivalent field of view.

Also, see more Mirex threads here:

Well, it depends. If you're used to shooting an 80mm lens on a 645 body where it's a normal lens, then you'll see a 'crop factor' effect when you shoot that same lens on a full frame (FF) DSLR, where it's a short telephoto lens. If you're used to shooting only with a FF DSLR, then the angle of view (AoV) from an 80mm M645 lens on the FF DSLR will be the same as the AOV from a "35mm" 80mm lens, on the same FF DSLR. Of course, the m645 lens has lots of "image circle" left over for shifting and tilting the lens, and that's why you get the Mirex.

The Mamiya M645 C 80/2.8N is a fantastic lens on a DSLR. On a 1DsIII, the lowly 80/2.8N is just as sharp in the centre and sharper in the corners than both a Contax Zeiss Planar 85/1.4 and Leica Summicron-R 90/2 E55, and that's no small accomplishment.
