I would appreciate info.re. a 350ml-f10 Wollensak raptar process lens mounted in a rapax shutter.( I assume it was used on a view or field camera) What could I expect from this lens re. sharpness best f. stop and focussing ability,especially at infinity? How much bellows extension would I need at infinity. Thanks John.

John, For infinity focus you need about 13.75 inches of extension. As a process lens it should be sharp enough (though I have no experience with this particular version). As far as the best f-stop, performance should be pretty good even at f10, with possible slight enhancement at one or two stops down.
