Dammit. Now I just realized that my M8 has the same damned problem. I'm very frustrated about this because 1) I got this camera from Tamarkin, who bought it with a group of other demo M8s FROM LEICA, whom you would think had checked this before shipping them out, and 2) I checked in detail when I got the camera and didn't see any evidence of it at the time. 3) I also changed the covering to griptac.
So what should I do here? I pretty much never use the camera above 640, so, to be honest, I will rarely encounter the problem. at 640 there is no line--just the single hot pixel that is causing it. I have a 1-year Leica warranty, so should I wait until the warranty is nearly up, THEN send it to leica for repair? If I'm not mistaken, this will add another year to my warranty, right? And finally, changing the covering, if I remember right, does NOT void a Leica warranty, correct?
I don't especially miss my R-D1, but I certainly miss its hot pixel correction function now. I don't understand why Leica doesn't put this into the firmware. Perhaps it will, in the next version.
