The spotmatic has a torn shutter curtain. I haven't tested the meter yet. I shot a successful test roll with one of the F-1N bodies once I taped over the holes on the bottom. Today I shot most of a roll of Ektachrome Elite Chrome 100 with it. Someone on eBay is selling all three bottom caps separately for a total of $75 (+ shipping). The camera only cost $25 so I think I'll stick with the tape for now. The F-1N doesn't have an exposure lock when the camera is used in Aperture Priority mode. For this reason I prefer using it in stop down mode. It's a little easier in some situations than the F-1 or F-1n because I can make adjustments to the f/stop without looking away from the finder.
