davidbaddley Posted March 6, 2017 Share #21 Posted March 6, 2017 (edited) Advertisement (gone after registration) I got both the M9 and the MM1 shortly after each was released, and have never had any sensor corrosion with either of them. I live in Salt Lake City, which is very dry, extremely low humidity. I travel with them to moist climates, but never for more than a few weeks at a time. I suspect it's my dry climate that has kept them fresh. - David Edited March 6, 2017 by davidbaddley Quote Link to post Share on other sites More sharing options...
Advertisement Posted March 6, 2017 Posted March 6, 2017 Hi davidbaddley, Take a look here Informal Survey--Monochrom Sensor Corrosion. I'm sure you'll find what you were looking for!
fotografr Posted March 8, 2017 Author Share #22 Posted March 8, 2017 (edited) Well, it turns out the camera I bought did have the corrosion issue. I didn't see it at first but as soon as I did a complete test it showed up very clearly. So today I shipped it to New Jersey for sensor replacement. I'm actually kind of glad to be getting this out of the way so I won't have to worry about it anymore. I have a feeling that the person who sold it to the company I bought from knew the sensor was bad and didn't want to deal with it. That's fine with me because once I get it back it's going to be like having a brand new M Monochrom. Edited March 8, 2017 by fotografr Quote Link to post Share on other sites More sharing options...

A little separation anxiety, no doubt, but time flies and it will be back before you know it. Just like new. John Quote Link to post Share on other sites More sharing options...
Alberti Posted April 8, 2017 Share #24 Posted April 8, 2017 Do I understand correctly normally you will not see it but only at smaller than F/11? Well, it turns out the camera I bought did have the corrosion issue. I didn't see it at first but as soon as I did a complete test it showed up very clearly. So today I shipped it to New Jersey for sensor replacement. I'm actually kind of glad to be getting this out of the way so I won't have to worry about it anymore.

That's fine with me because once I get it back it's going to be like having a brand new M Monochrom. What is that complete test? When I did sensor cleaning test (F/22, grey desktop) I saw many black dust spot, but also a few with light edges. I assumed these were artifacts from the processing (sharpening) but now I am not so sure anymore. albert Quote Link to post Share on other sites More sharing options...
tollie Posted April 15, 2017 Share #25 Posted April 15, 2017 My beloved Monochrom, which I purchased used, began to show signs of corrosion within 6 months of my ownership. The previous owner lived in Florida and I live in Puerto Rico. It was clean and had a recent CLA when I purchased it. I struggled along until the corrosion was too profound to ignore... this was sometime in the early fall 2015. Off it went to Leica NJ for going on four months until a new batch of sensors arrived. It was shipped back to me in January 2016. Sadly signs of corrosion returned about 10 months later. I held on until a week ago and sent it up to Leica NJ. Leica NJ tells me that it will be between 10 to 12 weeks to replace the sensor. I think the climate here (hot and humid) contributes to the rapid corrosion. I understand that the new sensor replacements will not corrode... I hope that is the case. I'm thinking that I should consider another type of camera... perhaps a used S2 Any suggestions?

james.liam Posted April 25, 2017 Share #28 Posted April 25, 2017 After only 18 months of use, my MM v.1 started to show sensor rot. Just got an email from NJ that its ready after a 12 week wait. Quote Link to post Share on other sites More sharing options...
Alberti Posted April 25, 2017 Share #29 Posted April 25, 2017 (edited) From earlier examples, I think I have at least one spot, that stays even though cleaning. It is invisible upo to F5.6, and I only go beyond with wide-angles. This is a 100% crop of the left top image area; the spot I placed in the middel. I disables sharpening and noise reduction (the latter should be disabled anyway for 320 A on the MM1 in C1). Welcome, dear visitor!

It looks like it is like the other example in this thread with small pox: the edges, the shape, the light borders. "Standard" dust is hard, and moves from time to time. this is stationary.

Also it does not show up when shooting 5.6 and wider... so there is that. I understand that the corrosion grows over time... so keep an eye open if you decide not to send it in.

Mine had quite a few of those and the sensor was replaced. I cloned them out for a while but it soon became too much. I waited until winter, when I shoot less, so the wait wasn't so bad. .

LeicaPassion Posted June 20, 2017 Share #37 Posted June 20, 2017 Leica should set up a simple system where the body is sent in a week or so befoe the actual repair, the work is done within a few days, and the body is sent back. It's ridiculous that a body sits for weeks or months at Leica collecting dust while waiting to be serviced. This is Management 101. Quote Link to post Share on other sites More sharing options...

You should actually hope for the problem to occur in your M9 before the cutoff date of August 15. What are you being told at this time about when to expect your MM back?

Etruscello Posted June 21, 2017 Share #39 Posted June 21, 2017 I purchased an MM1 in 2013. There is no sign of corrosion, even when examined at f16 against a bright sky. I live in NY. About 2 years ago, I was caught in a forest rain storm during a shoot with the MM1. I kept it covered in a plastic bag and occasionally took it out partially for a shot or two. I thought for sure that would start the corrosion problem. Not so. Tom Quote Link to post Share on other sites More sharing options...
mwilliamsphotography Posted June 22, 2017 Share #40 Posted June 22, 2017 Be warned. I was given inside info that all these CCDs will eventually suffer corrosion. Not IF ... WHEN. My M Monochrome was one of the first shipped to the USA ... it was fine until I noticed the corrosion in some shots taken in Jan of 2017 the extent of which surprised me ... I went back and reviewed images taken in fall and winter of 2016 and it was already starting to corrode. It only took a few months to spread over the whole sensor. Mine has been fixed and the camera is as new. If you see any sign, be it just starting, send it in immediately ... do not live with it because it WILL spread. If you wait you will end up paying for a repair that you should never have to. - Marc Quote Link to post Share on other sites More sharing options...
