jaapv Posted November 13, 2014 Share #2 Posted November 13, 2014 Brand new M-240 has sensor problem… I'm apparently not the only one… Leica M (240) sensor fault?: Leica Talk Forum: Digital Photography Review Hmm.. typical DPR. A confusion of vertical stripes (brand independent) and horizontal ones (undetermined but most likely a sporadic problem) Leica replaces/remaps free of charge though...

JHAG Posted November 13, 2014 Author Share #3 Posted November 13, 2014 I was in Wetzlar 10 days ago to have the M240 frontfocus rectified and controlled with all my lenses. Couldn't they double check this ? Really… Now I will have to send it in, wait who knows how much time to get it back. Absurd. Quote Link to post Share on other sites More sharing options...
jaapv Posted November 13, 2014 Share #4 Posted November 13, 2014 We don't get many misfocus out of the box complaints any more. Not good. Quote Link to post Share on other sites More sharing options...
JHAG Posted November 13, 2014 Author Share #5 Posted November 13, 2014 Rangefinder was totally off. Yes , they did it on the spot. They could have checked sensor line too under various lights. 1 Quote Link to post Share on other sites More sharing options...
bocaburger Posted November 13, 2014 Share #6 Posted November 13, 2014 In the past, Leica (USA) and the indie repair people mostly refused to repair isolated issues, instead requiring a complete service along with. They did it to avoid having to tear the camera down again at their expense, but at the same time it avoided extra aggravation and downtime for the customer too.

lethbrp Posted November 14, 2014 Share #7 Posted November 14, 2014 Advertisement (gone after registration) Brand new M-240 has sensor problem… I'm apparently not the only one… Leica M (240) sensor fault?: Leica Talk Forum: Digital Photography Review I had that problem on my first M240. It was only present at ISO 640 for some reason. Leica replaced the camera for me, the the replacement wasn't without its faults, the rangefinder was off a little. So eventually, they sent the second camera back to Germany for adjustment. I do love the camera, but as someone who converted from DSL (Nikon), I had nowhere near the technical issues I've had with my Leica equipment. 1 Quote Link to post Share on other sites More sharing options...
viramati Posted November 14, 2014 Share #8 Posted November 14, 2014 If this is a brand new camera I would have thought that your dealer should just replace it with a new one. 9 Quote Link to post Share on other sites More sharing options...
Jeffry Abt Posted November 14, 2014 Share #9 Posted November 14, 2014 I had such a problem with my first digital M (the M8). I returned it to my dealer for a replacement. They sent me a new one ...all turned out well! Quote Link to post Share on other sites More sharing options...
bocaburger Posted November 14, 2014 Share #10 Posted November 14, 2014 I do love the camera, but as someone who converted from DSL (Nikon), I had nowhere near the technical issues I've had with my Leica equipment. I guess I've just been lucky so far, because in 45 years of using Leicas I really haven't had much trouble with them, including M8, 9 and 240. Can't predict what might happen tomorrow of course.

Guest Gop Posted November 15, 2014 Share #11 Posted November 15, 2014 We don't get many misfocus out of the box complaints any more. Not good. Hey Jaap, my "M" had serious back focus out of the (sealed) box and a mini "Sahara" on the sensor... Quote Link to post Share on other sites More sharing options...
tobey bilek Posted November 15, 2014 Share #12 Posted November 15, 2014 dead pixel problem. Unaddressed Leica problem since forever. You would think they should be immune to this by now. Quote Link to post Share on other sites More sharing options...
jaapv Posted November 15, 2014 Share #13 Posted November 15, 2014 Digital problem. Solution: shoot film. 1 Quote Link to post Share on other sites More sharing options...
bocaburger Posted November 15, 2014 Share #14 Posted November 15, 2014 (edited) It is a digital problem, obviously, as film cameras don't have pixels, so obviously the only 100% solution is to shoot film. Other cameras have user-accessible remapping utilities though, which at least mitigates needing to ship the camera back and wait weeks for a simple operation. I personally would be willing to sign a waiver to Leica stating I acknowledge I might lose some theoretical performance by using the remapping utility instead of having them replace the sensor, if as you've stated before, that's Leica's beef with providing it in firmware.

indergaard Posted November 15, 2014 Share #15 Posted November 15, 2014 It is a digital problem, obviously, as film cameras don't have pixels, so obviously the only 100% solution is to shoot film. Posts about dead pixel lines requiring a trip to the repair shop are quite common on Leica forums, but not on Nikon, Canon or Sony forums though, not even taking into account how many times the volume they sell. In fact I've never seen a report of it, but I'm giving it the benefit of doubt. Nikon, Canon and Sony's are affected by the same issues. The only difference is that the electronics in their cameras are capable of doing auto-mapping in-camera, so you don't have to have the camera serviced to re-map the sensor. Leica aren't really on the forefront of electronics compared to the other big manufacturers. Although they have adapted a film camera and lenses to digital in an elegant way - they still have a long way to go in regards to electronics, software and in-camera processing capabilites compared to most other manufacturers.

Hmm, I think only on the lower-end models: Let me google that for you Top-end cameras have a limit to the number of pixels that can be mapped out for quality reasons. After that the sensor must be replaced. Quote Link to post Share on other sites More sharing options...

After that the sensor must be replaced. That makes sense. And honestly, I would rather prefer to have the sensor replaced myself, rather than knowing that I have lots of pixels that are wasted. I would appreciate quicker turnaround times for the service though 2 Quote Link to post Share on other sites More sharing options...
bocaburger Posted November 15, 2014 Share #18 Posted November 15, 2014 (edited) I would appreciate if the re-mapping utility simply counted the number of good pixels and remapped until the limit was reached, then throw a message "Pixel Mapping Limit Reached, Further Mapping Can Result In Decreased Image Quality....Continue? YES/NO". Edited November 15, 2014 by bocaburger Quote Link to post Share on other sites More sharing options...
jaapv Posted November 16, 2014 Share #19 Posted November 16, 2014 Difficult to implement, as the original pixel mapping of each sensor will be different.... Quote Link to post Share on other sites More sharing options...
bocaburger Posted November 16, 2014 Share #20 Posted November 16, 2014 Difficult to implement, as the original pixel mapping of each sensor will be different.... I'm not sure why that would matter. If Leica has a hard number cutoff for the minimum number of live pixels allowable below which they replace rather than remap, then an in-camera utility should be able to make the same determination.
