I have the f12.5 version of the Extreme Wide Angle Velostigmat Series III, 6 1/4. It is tiny and very wide, for my tastes. Sometimes, however, it has been useful. The following image has been taken with it:



It allows some movements on 8x10. I don't enlarge my 8x10 negatives, but the image quality is really good enough for contact printing. With movements, though, the image degrades on the outer parts of the field.

Since it is so tiny, it can stay, reversed, in my Wehman camera when folded. I always carry it with me.
