180mm symmar-s on 8*10?

[stehei]

Had anybody ever tried this combo?
I know the lens is meant for 5*7, but when stopped down,
does it cover 8*10 inch?

Any help would be very much appreciated!

regards

Even the 210mm Symmar-S is being pushed to cover 8x10.

The Symmar-S 180mm has an image circle of 252mm at f/22. For 8x10" one needs an image circle of 312mm at least.

It will not cover, but image circle specs are often conservative. As Gene mentioned the 210mm Symmar-S will cover 8x10, but Schneider says it only has a image circle of 294mm at f22, go figure.
