Im currently shooting a Eastman View No. 1 with a "no name" 12 inch lens. The combination actually fits me, but im limited to shooting extended exposure since I don't have a lens with a shutter. I simply use the lens cap as the shutter for long exposures. However I would like to get into shooting some faster speed films during the day. My question is, should I simply buy a lens with a Copal shutter, or upgrade the whole system? Im no pro, and will probably never have a showing, or sell my stuff, so cost is a bit of a factor. I would love any suggestions. Thanks
