I have found a Tominon 105mm lens on a Polaroid copal #0 shutter f/4.5-32 1 to 1/125 that the seller says is a coated lens. will this work on a calumet 4x5?

Sort of. It should be nice at 1:1 or there about. At infinity, it will illuminate 4x5 but will be unacceptably soft around the edges.

Cheers,
Mark

In my opinion these are superb close up lenses. If you want to try close ups buy it at a sensible price, bear in mind that many/most of these shutters do NOT have a diaphram so any lens that you intend to screw into them needs an independent diaphram.

No way except as a macro lens.

Pete, Bunster0 has an inexact way about him that makes clear responses to his questions impossible.

FYI, there are at least two versions of the 105/4.5 Tominon. I'm acquainted with two of them. One, for the Polaroid MP-4 is in barrel and is intended to be front-mounted on a Copal #1 press shutter without diaphragm. That's the one you're thinking of. There's another for the Polaroid CU-5 that is mounted in shutter. The CU-5's version's shutter has a diaphragm.

Cheers,

Dan
