I'm not sure exactly wha tyou have but I will assume you have an Optar in a Kodak Supermatic shutter, an Optar in a Graphex shutter and a Zeiss Jena in an unkown shutter. If this isn't true, then post again and we can figure this out.

If both are Optars then it will the the condition--coating scratches, etc that will determine which to keep. The Carl Zeiss Jena is probably uncoated and would be the lesser of the three lenses.

I seem to have better luck with Graphex shutters over Kodaks scattermatics, but I know others that are just adamant about Supermatic shutters.

If you have the capability I'd shoot a transparency with each lens at the most used apertures 8,11,16,22 and look at each under a loupe. The sharpest one wins. If you don't have access to transparency film, use black and White film, and look at the neg with a light box and loupe.

To Fishhead
I agree with Les about the superiority of the Graphex over the Kodak Supermatic shutter, and my only comment would be to see whether the lens elements would interchange between the two shutters. If so, this would enable you to put the best elements on the Graphex. In case you haven't done this before, the elements unscrew ccw (a rubber-pad jar lid remover works well). Don't force anything!

The zeiss lens is in an old compur shutter.

It is not a good shutter, old and worn out.

What are my chances of switching the lens elements on this one?

I don't think the Zeiss is coated... but then again I thought the graflex lenses had an L after the serial number if they are coated. Mine does not, but it looks coated.

Can I post a picture of the Graflex somewhere?

It's rare to find a Zeiss Jena that's coated. Most likely this lens is pre WWII. After the war it was difficult to get Jena lenses here. (They were miffed that we bombed the factory into oblivion) All of these lenses are Tessar formulas, so I say dump the Jena on ebay, test the other two and use the best. The coated lenses will have less flare and a more accurate exposure since more light gets onto the film. (Transparency film uses E-6 chemistry like Ektachrome slides, if you don't already have access to it, it's too expensive to start. Test with B&W film)

The information you posted is generally very good... the Kodak Ektar and the Zeiss Tessar are both....Tessar formula lenses. The Graphic Optar is a Tessar formula with some changes to give the lens a tad bit more coverage for using the minimal front lateral shift and vertical rise.

The reasons lenses from that Zeiss Jena factory were hard to get after WW II..after the factory was rebuilt...was that it was in EAST GERMANY..and there were considerable import restrictions. There were also patent battles between the East German plant and western "Zeiss" companies. Jim

It depends on which size camera you have (2x3, 3xr4, 4x5?) and on how you see landscapes. If you shoot landscapes on another format and know what focal length you prefer there, pick one for your Graphic with the same horizontal angle of view.

You've asked a very personal question that only you can answer for yourself.

Cheers,

Dan
