My first guess would be a little dirt or corrosion on whatever shaft the shutter speed dial uses to ride up and down on. If this happens intermittently when the outer ring has not fallen far enough, I would, first of all, apply my favorite cure for corroded surfaces. Raise and lower the outer ring about 50 times in succession. Just keep doing it, and see if the shaft frees up enough to allow the ring to drop down all the way. If lots of exercise doesn't improve it you probably will need either to disassemble it or live with it, but your observation that you can get the outer ring to turn by pressing it down suggests that the problem might be minor enough to respond to exercise. |
