I currently shoot with a Nikon D40. You can see my equipment in my sig. I currently have two main questions. 1) Since my lenses are DX, will they work with a Nikon film SLR? and 2) How big of a print can I expect to get out of a good shot on 35mm film? I know ISO will vary that somewhat, but let's say a nice low ISO of 100-125. Any help is greatly appreciated. Thanks!
