I just screwed a fairly good quality (sony) 1.5 video teleconverter to the fron t of my Schneider 270 telephoto. Looking at the ariel image of a resolutation c hart through a 6X loupe, things look pretty good. I very seldom need a 400mm, a nd this looks like a cheap (and light) compromise, or do you think I would be be tter off just using the 270 and cropping down to a 400mm image? I also have an old (90yrs) 8X10 lens that I could use the back element off of, to get over 400m m but I suspect this would be better than that?
Has anyone else played with this?
