How good are the Osaka line of large format lenses? Does anyone actually use the m? Are they a good deal? I've heard that they're just like the old classic Kodak and wollensak designs, except that they have modern coatings and new shutters. Thanks for the information.

I think they may be the same as the Congo lenses. If so, here is the website: http://www.cosmonet.org/~congo/index_e.html

I recently had confirmation from Mr Yamasaki that they are Congo Yamasaki lenses . I have not owned any but have read good comments on their quality. They can be purchased directly fro m the factory at interesting prices.

Congo & Osaka lenses are 4 element 3 group tessar type lenses. It's a classic lens formula & fairly sharp. They don't have as much covering power as some other lens formulas, so if you buy one, look carefully at the coverage. I have an older 180 f/6.3 Congo that I'm quite happy with. I use it on 4x5 and 6x9. I tried it on my Grandfather's 5 x 7 & it worked ok, as long as I limited my tilts.

There is a review of some of the Osaka lenses, including comparison with some Schneider and Rodenstock lenses, in the Sept/Oct 1997 issue of View Camera magazine: "Cheaper Glass: Lens alternatives for 6x9 and 4x5". You can contact them at http://www.viewcamera.com/

I own a 210mm 4.5 Osaka Commercial lens. It is as you said a tessar formula with modern multicoating and copal shutter . It is sharp and contrasty and works well for my black and white work on 5x7 format. It is mounted in a copal 3 shutter which is large but easy to use. I can't speak for their usefulness for color work but I was told that they perform well. Overall a great lens for a reasonable price. I would buy one before an old Kodak commercial Ektar which is not muticoated and the shutter may be a problem and you will probably spent less money. I also shoot with 240 and 300 mm Fuginon A lenses and would said the Osaka just as sharp. Also the 4.5 apeture is sure nice to focus with. The Fuginons are F9s but much smaller and lighter.

Not all Osaka/Congos are Tessar types. They make wide angle double gauss lenses as well (like the WF Ektars), and a soft focus lens too.
