Bernard Shakey Posted September 3, 2020 Share #1 Posted September 3, 2020 Advertisement (gone after registration) My M6 has a discoloured Shutter Curtain. Is this a problem and sign of deterioration or nothing to worry about? There are no holes in the curtain. Thanks. Welcome, dear visitor!

adan Posted September 4, 2020 Share #2 Posted September 4, 2020 Leica film shutter curtains are made of rubberized cloth (for light-tightness with flexibility). The rubber will oxidize and turn gray over time, just like rubber focusing rings or car tires. It is not an immediate concern (many Leicas show this while still working fine) but bears watching since eventually (decades?) the oxidizing rubber may stiffen and be subject to cracking as it wraps around the curtain spools. And eventually leak light. The curtains can be replaced, but it requires a major strip-down (time without the camera, money), so something to be put off until really necessary, or combined with other cleaning and adjusting by a tech. Some of the history buffs here may have a better handle on the exact time-frames. 1 Link to post Share on other sites More sharing options...

Bernard Shakey Posted September 23, 2020 Author Share #5 Posted September 23, 2020 Good to know thank you. I've just sold a kidney to get the M6 so just wanted to be sure. The quality is just amazing. Very pleased. Welcome, dear visitor!
