If reading and metering , especially in auto, is ok this does not indicate there is anything wrong with it. I have found some meters were just like that in cameras that had never been open for repair. Some explanations may be of some help: #1: the position of the needle decides about the aperture opening (not what you read on the scale), and the correct functioning of preventing over- and unerexposure, this set-up is called the needle trap mechanism. If, for some reason, the travelling of the needle is blocked before it reaches its end positions, the system cannot work the way is is supposed to. #2: the needle is made to stop on both ends of the scale by bumper stoppers which to some degree can carefully be bent for correction if necessary #3: the aperture scale on top of the housing can also be adjusted relative to the swing of the needle #4: other problems can cause this problem, like dirt in the FRAGILE coilsprings in the meter, when there is metal debris caught in the magnet of the solenoid or the camera has other mechanical linkage issues (bent levers, etc.); in the S2 with its top cap off everything is easy to understand how it is supposed to be working, as one can actually see what is happening: the meter housing is see-through plastic and the leverage is visible. |
