Repro-Claron 355mm f9 evaluation and fit : LUSENET : Large format photography : One Thread

Does anyone know whether a Repro-Claron 355mm f9.0 lens is a direct screw-in fit to the Copal 3 shutter? Also any comments as to how this lens compares to the later design G-Claron of the same focal length would be also greatly appreciated. My proposed use would be mainly at or near infinity for natural landscapes with an 8x10 camera. Thank you!

Check Steve Grimes' website. He has a table that shows what lenses fit on Copal shutters.

As far as I know they won't go in a Copal 3. I bought one in barrel and then bought a clean 210 4.5 Xenar for the shutter. Shutter is the old Compur DRGM Compound. It is a pleasing combination. They cover 8X10 with some movements but nothing like the later 355 G-Claron. The repro Clarons are the same formulae as Artars and Ronar's and have similar coverage, probably a little more. Schneider didn't put any mechanical vignette in these because of their intended purpose I suspect. Therefore beware. You'll see image where there really isn't any. Gets very fuzzy out past a certain point and sometimes it's difficult to tell when you're getting there. Later 305's I've seen were able to go into Copal 1, whereas my 305 is in a Compur 2. The same may be true of the 355's. Later ones may go into Copal 3. I'd like to hear from anyone that has a REPRO-Claron in Copal 3 for my info too. The 355 in Compound is a very pretty lens in my estimation. I enjoy the classic "look." That final statement probably won't find much sympathy in this crowd.

I have a 420 mm repo-claron which was a direct fit in to a copal 3. It is a late model with serial number 11,521,346 with a black element housing. I think that the later models will fit into current shutters the same as late model g-claron lens.

Thanks to all who responded, I really appreciate your input and advice. I backed away from a specific lens being offered on ebay as the seller could not confirm to me that it was a direct fit and if it was not the cost of mounting to Copal 3 would be a bit much. Will be on the lookout for a G-Claron 355 or, better yet, a Fujinon A 360mm - haven't seen one of these in awhile. 360mm seems to be the perfect angle of view on an 8x10 to frame certain mountain shots. At times my 305mm G- Claron is too wide and my 450mm Fujinon throws too narrow a field.

I have the new G-Claron 355/9. I use it as my longest lenses for my Zone VI 4X5 camera. It is quite heavy. I photographed New York skyline with this lens from Brooklyn for four years. This lens very sharp at infinity at f/16. I did not need to stop down to increase sharpness. It is often said that you have to stop down quite a bit w/ process lenses. But my records shows that f/16, 2 to 3 minutes after sunset w/ velvia. I purchased the lens from old Zone VI Studios after I read late Fred Picker's comments on this lens in the Zone VI newsletter and it came w/ a Copal 3 shutter. Hope this helps.
