FS: A quartet of 210mm lenses in Copal shutters. CW from top right, Computar Symmetrigon, Rodenstock Geronar, Osaka Commercial, Caltar-S II.
All need a good cleaning and dust removal. The Computar looks to have a couple of very small scratches on the rear glass. The Geronar is a triplet, the Osaka is an f6.3 Tessar type (there's a reason they used the word Commercial in the name), the Caltar -S II is a rebadged Symmar-S (and the only Plasmat of the lot). Im not sure what the construction of the Symmetrigon is but its a big beast (partly due to the removable hood). The Geronar is in a Rodenstock labeled, all black Copal. The others are chrome ringed. All have retaining rings. None have caps (actually, the Rodenstock has a rear cap)
I checked the shutter speeds with a Calumet tester. All are within 1/6 stop at 1 second. I didnt check the numbers for the rest of the speeds except to note that they all seem to be 1/6 to 1/3 stop up to 1/60s and then begin to deviate a bit more. I didnt notice much difference in speed on any of them between 1/250s and 1/400s. I can provide the timings if you want them.
Looking for $175 net to me for each.
Thanks,
Dan
