i find i now have a collection of used lenses in shutters, shutters which are de cades old, and who knows how accurate they are??? once, i saw this guy at used c amera store testing a shutter with a device that looked home made, and it used a strong light bulb as a component. and he could plug this thing into a wall sock et, sit the lens under the lamp and fire the shutter and tell what speed the shu tter was firing. do any of you know what devices for testing shutters are avalib le and/or how one would find such a device? thanks
