During a recent trip I found that my M6's rangefinder focussing patch was/is out of alignment/adjustment. I did not bump it or drop it, it just seems to have gone out of alignment. Perhaps it was all the vibration from the car/plane trip. <p> The split image lines up correctly on the horizontal axis, all the way out to infinity, but not on the vertical axis. It did not affect my images and accurate focus is still possible, but it bothers me to see an out-of-alignment image in the viewfinder. <p> This one is my newest M6 (non TTL), still under the Leica Passport warranty. I've never had this problem with any of my other Leica bodies. Any idea how complicated a repair/adjustment this is? And how long does Leica usually take to repair these things under warranty? <p> Thanks for the advice/help. Sergio.
