Asahi Takumar 135mm f2.5 darkroom and the crossbar accommodates backdropsThis Asahi Takumar is actually a K mount lens, not a screw mount, so Spotmatic users will want to avoid this one. But if you've got a K mount camera, this is a nice short telephoto lens in pretty nice shape, but for a small ding in the filter ring. Focusing is good, with very light hesitation. Clean glass, good function.
