Mike Shimwell Posted December 27, 2013 Share #1 Posted December 27, 2013 Advertisement (gone after registration) Hello All I thought I'd report that my M9 woke up the other day with a cracked sensor cover glass. I spotted it downloading pictures yesterday and have emailed Leica to ask if they will repair without charge. For the record, the serial number begins 3906 and the camera was bought new in October 2010. Never dropped, bumped or maltreated. I will keep the forum updated with progress. Hopefully they will repair quickly and without charge. Meanwhile it's Monochrom and MP/Ikon... Happy Christmas all Mike Link to post Share on other sites More sharing options...

Mike Shimwell Posted December 27, 2013 Author Share #2 Posted December 27, 2013 Actually, that leads to a question - should I worry about the monochrom? Have there been any examples of sensor glass cracking in the MM as opposed to the M9. I suspect some ME ownders may also be interested in their camera's record too.

Paulu Posted December 27, 2013 Share #3 Posted December 27, 2013 I have a very similar problem. I was travelling in Mozambique and Namibia in October/November when I realised that all my M9 images suffered from what look like a mosaic cracking. It was a tiny fragmented pattern that destroyed skies and anything that had a simple clear colour. On returning - thankfully I was also carrying a Canon whilst travelling - I took the camera to Leica Mayfair who immediately saw the problem. The M9 was returned to Leica and I am now told that the entire covering of the sensor has come broken away. Again, no particularly rough or dumb usage on my part - simply a failure. I am waiting for the repaired camera but have lost confidence in the M9 and am now wondering about selling the set, lens, monochrome etc and going for a more reliable machine. Will keep you posted. It feels like the end of a love affair. Link to post Share on other sites More sharing options...

keithlaban.co.uk Posted December 27, 2013 Share #5 Posted December 27, 2013 What is it that causes this problem? Link to post Share on other sites More sharing options...
Mike Shimwell Posted December 27, 2013 Author Share #6 Posted December 27, 2013 Thanks Jaap - that seems to be good news, although it may just be smaller numbers of course. Paul, I understand, but am waiting to find out Leica's response. Good service is a powerful equaliser and I don't really want to go back to my Canon 1Ds3 or modern equivalent. Keith, I don't think any explanation has been given, but mine looks like this (bottom right of frame) Mike Link to post Share on other sites More sharing options...
jaapv Posted December 27, 2013 Share #7 Posted December 27, 2013 Advertisement (gone after registration) I have a private theory - the problem appears to me to be in the bonding of the various layers of the sensor. The IR filter is thicker thus more rigid than the M8. If the bonding layer between the layers is marginally too thick in production the expansion/contraction caused by thermal cycling (aka the activating of the sensor to take an image) will induce repeated stress into the IR filter causing it to crack in the end. The M8 cover glass, being thinner thus more flexible, will not reach this point, the MM has a different structure due to the Bayer filter being replaced by plain glass. Just my theory though….
