Does anyone have any opinions as to the quality of Congo lenses? Also, are they imported out of Japan or should arrangements be made directly with the factory?
Do a search on lfphoto.info - there are some results over there.
I'm not sure if you can deal directly with the factory or not. Regarding quality, I think their Q&A is somewhat weak - you may get a dog of a lens, or a good one - seems to be random. They are cheap, but in this case, you may get what you pay for.
Badger Graphic used to carry them, but they don't appear to carry them any more.
Kerry Thalmann had several Congo lenses that we looked at. The QA seems to be somewhat variable. But they offer a couple lenses you don't see from the "big names" (90, 120 wide field lenses that are small and multicoated, and the 150mm soft focus).
For the money, picking up a used lens from one of the major manufacturers might be a more consistant, predictable way to proceed.
