Another potentially unwelcome side effect of this mechanism is that if you want to rely on the on board meter, you will only ever get it to work on exactly 36 frames from a 36 frame roll.
e.g. my Olympus OM2N is up and running, meter and all, as soon as you clip the film in and close the back, and I've been getting 38-39 'metered' images out of a roll in many cases (e.g. Foma spools a little more film in their Fomapan 200 than needed for 36 images).
Of course you could set your FG on 'M90' and shoot away+guesstimate exposure until you hit frame '1' .
