Folks:
I have two different copies of the Schneider G-Claron 240mm f9 lens. One has a serial number in the 11.9M range and has a ~46mm thread. The other has a serial number of ~14.1M, and has a 52mm thread. From what I have learned by checking previous posts, the earlier one is a Dagor type (6/2) and the later one a Plasmat (6/4). The IC of the older one is given as 321mm and the newer one as 298mm although many folks claim to get much larger IC's as you stop down. How much larger seems to be a subject of some dispute. Some very big numbers have been suggested.
My question is, has anyone actually used both of these lenses and have an opinion on which performs better? I will not be getting an 8x10 camera for a while (it is on order) and I was wondering if it made sense to get the Dagor mounted into a shutter or is the Plasmat going to be a superior performer? My assumption from my reading is that both are likely to be single coated although if anyone knows otherwise, that would be useful information as well.
Thanks,
Dave B.
