LouK Posted May 2, 2012 Share #1 Posted May 2, 2012 Advertisement (gone after registration) Two of my four Leica lenses are not being recognized by the M9 camera. My 50mm and 75mm bought new in 2009 came with lens marking and are recognized. The 28mm Elmarit-M and 35mm Summicron-M are not being recognized. The 28mm Elmarit-M was also bought in 2009 and came with lens markings. The older 35mm Summicron-M was sent to Leica in 2010 and markings were added. I cleaned the sensor but it did not help. The 35mm and 28mm is being recognized by my M8.2 ( but not the M9). Any suggestions? Link to post Share on other sites More sharing options...

jaapv Posted May 2, 2012 Share #2 Posted May 2, 2012 Are you sure the lenses are clicking in upon mounting If you press the release button you can overrotate them or if you do not turn them into the click, they won't be recognized. Worst case scanario is an IR LED dying. Link to post Share on other sites More sharing options...
LouK Posted May 2, 2012 Author Share #3 Posted May 2, 2012 You may be right that it is a sensor problem as the lenses are being recognized by my M8.2. I tried taking the 35mm off and putting it back on again to the click but it did not work. Thanks Link to post Share on other sites More sharing options...
LouK Posted May 3, 2012 Author Share #4 Posted May 3, 2012 It seems my lens detection problem coincides with the latest M9 firmware update, 1.176 in early December and that may be the cause of my problem. Does anyone else have this issue? Link to post Share on other sites More sharing options...
250swb Posted May 3, 2012 Share #5 Posted May 3, 2012 You can test your theory by going back to the older Firmware. Steve Link to post Share on other sites More sharing options...
01af Posted May 3, 2012 Share #6 Posted May 3, 2012 When my M9 was new, I experienced occasional cases of non-recognised (albeit 6-bit-coded) lenses. Removing the lens and re-mounting it usually solved the problem. I developed the habit to check the INFO screen each time after switching lenses. Lately, however, the issue seems to have gone all by itself. The reliability of the lens recognition feature seems to have improved—I have no idea as to why. The camera originally came with firmware v1.116. Currently it has v1.162 installed. Link to post Share on other sites More sharing options...
jaapv Posted May 3, 2012 Share #7 Posted May 3, 2012 Advertisement (gone after registration) 1.162 to be found here: http://www.l-camera-forum.com/leica-forum/leica-m9-forum/130720-m9-faqs-frequently-asked-questions-answers-2.html#post1919726 Don't use this firmware in conjunction with recent Sandisk SD cards.

tobey bilek Posted May 3, 2012 Share #8 Posted May 3, 2012 From the M8 these cameras have buggy firmware. I could not get the stealth mode to work, although there was latest firmware installed by Leica,2.14 I think. After a week or two, one day it just started working. My son has had the camera lock up if he filled the buffer which you would expect, but he had to remove the battery to clean it out. The off/on switch does not always wake the camera at first, but now seems ok. Raw+JPEG takes 10 sec to process, both his and mine. 133x Lexar cards. I have never seen an electronic glitch in the 5 Nikons I have. If I were not a Leica fan since 1980, I would have sold this thing and gone back to film.

jaapv Posted May 3, 2012 Share #9 Posted May 3, 2012 Nor have I in the four M8 and M9 cameras that were in my hands over the years. The write time is normal, although you might speed it a up marginally by using a card that is better matched to the camera, i.e. slower. The other glitches are certainly not normal and suggest that it is in need of some TLC in Solms. Link to post Share on other sites More sharing options...
StephenPatterson Posted May 3, 2012 Share #10 Posted May 3, 2012 Lou, you indicate that your 28 and 35 are not being recognized, while your 50 & 75 are. I do not know the exact version of each lens you own, but have you checked the 6-bit codes in these two lens groups for common bits? This might help you narrow the failure to a specific IR LED, which can only help Leica diagnose the problem if you have to send it in. As for write/buffer speed I only take DNG files, never in camera JPGs. No reason to drag the processor down with low quality files... Link to post Share on other sites More sharing options...
ho_co Posted May 3, 2012 Share #11 Posted May 3, 2012 Since you have an M8, you could photograph the front of the M9 to see if all the IR LEDs are working. Be sure to remove the UV/IR-Cut filter from the M8 when you take the picture. Link to post Share on other sites More sharing options...
mjm6 Posted May 3, 2012 Share #12 Posted May 3, 2012 You may have an IR emitter failure in the 6-bit sensor array, or it could be a reciever failure. I had the emitters fail last year on my M9... Anyone know if tere is a way to test the 6-bit sensor on M9? - The GetDPI Photography Forums I photographed the camera in the dark with a Canon G10 and activated the lens mount (I think it checks for the lens before taking a photo if I recall correctly, you'd have to verify that). Anyway, with the camera set to the highest speed, and then adjusting the image in PS, I was able to see the IR emitters. Only two were working. The other four are just barely visible in the original file. From the sound of it, you may have one not working, but by looking at the codes, you could tell if that is the case, since you have two that are working, and they may have common coding. The camera looks for the white bars (if it doesn't see a reflected IR light, then it assumes that the bar is black). Look at the codes for the two that work, and the codes for the two that don't. mark which of the bars are white on the two that work. collect both samples together. From this place: Leica M Lens Codes I don't know which 50 and 75 you have, co I cant collect the bars from that. Nor do I know which version of the other two you have. Note that it's the '0's in the list you need to collect (the white bars), not the '1's. Look on the back of the lenses to verify which codes you have. Suppose you have the 50mm Summarit, your code is: 101100 And suppose you have the 75mm summarit, your code is: 101101 You need to have positions 2, 5, 6 working for the 50, and 2, 5 working for the 75. However, if 6 weren't working, your 50 would be read as a 75 because the camera would only see the 2, 5 positions with the 50 on the camera, so you can verify that that position is working correctly with that test. All told, if both lenses are working correctly, you know that at least 2, 5, 6 are functioning correctly. You wil have to do this test for your actual lenses, not the codes I just used. Good luck on the problems. ---Michael Link to post Share on other sites More sharing options...
LouK Posted May 3, 2012 Author Share #13 Posted May 3, 2012 Thank you all for your suggestions. I reinstated firmware 1_162 and that did not work. I compared the sensor positions on my lenses and it looks as if position 1 or 6 is broken so I am sending the camera in for repair. By the way Mark Brady at Leica got back to me right away and also tried to be helpful. Again thanks so much to all of you. Link to post Share on other sites More sharing options...
kiteland Posted May 13, 2012 Share #14 Posted May 13, 2012 I had similar problem with my M8. Started with intermittent problems reading some lenses which got worse and worse as the camera approached 2 years old. Camera had a quick trip back to Leica and they replaced the “reader” Camera has been fine ever since Link to post Share on other sites More sharing options...
