Does anyone know whether a Schneider G-Claron WA 210 mm F10 lens covers the 8x10 format as a taking lens? What is its image circle? Good lens as a wide angle for 8x10? Thanks a lot!

I have one. It works great for 8x10 but movements are limited. Obviously stopping down to at least f22 is helpful and dare I say necessary.

Is there a f-10 G-Claron? I though this lens was a f-9.

schneider in germany just sent me some specs on this series (w.a. g-claron). the 210 is f11, i haven't heard of an f10 but there is a faster (f8?) 210 w.a. g-claron at lens&repro which no one seems to know about. the angle of view @ f22 is 86 deg. image circle @ f22 and 1:1 is 800mm - thus should be 400mm @ infinity. the filter size is 105mm. they are only listed as barrel lenses so if in a shutter it was most likely done afterwards. recommended for between 1:2 and 2:1. 4 elements in 4 components. the BIG problem seems to be performance at infinity - distortion grows rapidly as you get about 10 deg. out from the center of the i.c. it seems this lens is really only good for repro work.

To Mr. Hambrick's point. Spot On! Didn't even notice that. Mine is the f9.

OK, I bought the lens. But this is a "Schneider Kreuznach G. Claron W.A. 1/6.3 f'=210 mm". This is the actual labelling on the lens. The series number is 14,143,xxx, so it was made in 1985-86 period. The lens is mounted in a black rim Copal #3 shutter, aperture goes from 6.3 to 90, and takes 77 mm filters. The lens elements are single coated. I did not buy the F10 lens because it is in barrel (there is such a F10 lens!).

Still, I don't know the coverage power of this lens, even at F6.3, a Toyo 810M was run out of movements at infinity. I was told this lens will cover 11x14 wide open, and 12x20 at infinity when stopped down. I will check for distortion more carefully this time because I intend to use it for landscape.

Thanks for all your inputs!
