Swapping Graphex Optar Lens Cells

[Iskra 2]

Is it reasonable to swap Graphex Optar lenses (4.7/135) between Wollensak shutters. My newer lens/shutter assy has a bad front element, an older lens/shutter has a marginal shutter. Anybody know how tight the lens spacing tolerances were? Regards.

Should fit right in...I've never noticed shims, etc., on my Optar 135 f4.7!

If they are the same shutter, no problem. You can easily check the thickness of the shutters, at the mating surfaces, with a caliper. The thickness determines the spacing. Be careful about mixing the lens cells. Not a good idea. Keep them as original pairs.

Thanks for the quick responses!!! The older lens seems to have a bit less coating than the newer lens which should give it some more "glow". Regards.
