I have been looking at a used Sch. 210 f8, super angulon for sale. I have an 8x10 and been looking to move up to 11 x14 and I know this lense will cover 11 x 14. Will this lense cover anything larger than 11 x 14? Like 12 x 20? Also, is this lense generally hard to find used and is there much demand for the m? And what might be a good price range to buy it?
Second question: I'd like to experiment with portraits on 11x 14, I own a 20 inch B&L tele, f5.6. How much bellows draw might I need on 11 x 14 to get in really close, like head and shoulders?
