richfx Posted July 1, 2014 Share #1 Posted July 1, 2014 Advertisement (gone after registration) I've just purchased a used M7 - my first Leica film body (serial no. 28888***) - and the white metering dot on the shutter curtain appears to be rather dirty - a number of dark lines and spots / stains are visible, as shown in the attached photo. It seems that the light metering capabilities could well be adversely affected by this. Is this normal and if not, should I worry about it or return the camera? Thanks, Rich Welcome, dear visitor!

erl Posted July 1, 2014 Share #2 Posted July 1, 2014 The acid test is to shoot a film exactly to the setting that the meter gives you. If that is OK, then don't worry. Comparing the reading to another light meter may give you an indication, but many lightmeters don't agree with each other so that can be misleading. Also, be aware of variations in developing and by whom, to make the film assessment trustworthy. Already you can see there are more variables than your 'white spot' involved in the outcome! Your M7 is a later model so will have the upgraded VF, which is good. I would not be concerned about the small if any impact of the 'dirty' white spot. Remember it is not colour sensitive. Even new, the spot appears not 'perfect' judging by my three film M's. Link to post Share on other sites More sharing options...
pico Posted July 1, 2014 Share #3 Posted July 1, 2014 The instructions tell you that the spot is not supposed to be pure white. See page 96. "The metering field (diameter:12mm, i.e. approx. 13% of the negative’ssize) is situated in the center of the first shutter curtain. The unevenness of the white is not a result of poor manufacturing tolerances, but is due to the fact that a thick, complete coating cannot be applied to the rubberised cloth shutter curtain without the shutter performance being impaired. The irregular structure of the metering field in no ways affects the meter reading." . Link to post Share on other sites More sharing options...
richfx Posted July 1, 2014 Author Share #4 Posted July 1, 2014 Thank you both for your replies. I've seen other M7 and film body metering circles that are completely white, which raised my concerns. Rich Link to post Share on other sites More sharing options...

erl Posted July 2, 2014 Share #6 Posted July 2, 2014 I have 2 M6's and one M7. All three are different from each other. All expose fine IMO. Not an issue. As I said before, run a film through. That's the final test. Nobody wants to see your white dot, just your pictures! Link to post Share on other sites More sharing options...
