Got back roll of film which I shot with 35SP before sticky shutter was fixed. To my surprise I found 36 properly exposed frames(expected quite a few lost due to the sticky shutter). Used expired 800ASA film in poorly lit room ~7ev, meaning is 1/15 - 1/30 sec on f1.7-f2.8. Definitly like color and contrast, still need to decide whether it can compete in resolving power with OM/50mm combination. Overall I enjoi this camera, much easier to ficus in low light than OM.
