I have the chance to pickup a Leica M9 + Box, Leica strap, two batteries, charger, body cap for 1k. Only thing is the sensor has mild corrosion every 1-10 shots a photo pops up with two dots shown on the top right of the last photo.. you can visibly see the corrosion on the sensor aswell. Is this worth it on my end?
