Maybe-)) You really need to check the shutter. My old compur starts out the day at about 3seconds when set for 1second. Fire it about 5 or so times and the shutter is at about 1.5 seconds and constant. I bought an old 35mm last fall. When I got it 1 second was closer to 5 seconds. Spent some time watching TV firing the shutter and now the speeds are alot closer to proper. Not perfect but steady. Obviously the best thing would be a CLA but it does work.
