Wonka Posted November 24, 2009 Share #1 Posted November 24, 2009 Advertisement (gone after registration) Help. I just purchased a 75mm Summarit and I am testing it out now. However, when I looked at the info screen on my M9 it says "uncoded." What? My 35mm f/2 Summicron is read just fine by my M9. What's the deal? Then, I went to manual lens selection and noticed there are no options to select for the 75mm Summarit, nor are there any options to select any of the Summarits! What am I missing? The Summarits are 6 bit coded so what's the deal? Thanks. Link to post Share on other sites More sharing options...
Advertisement Posted November 24, 2009 Posted November 24, 2009 Hi Wonka, Take a look here M9 & Summarit Lenses. I'm sure you'll find what you were looking for!
Wonka Posted November 24, 2009 Author Share #2 Posted November 24, 2009 Anyone? I'm at a loss. I don't know if my M9 has a problem, whether the lens has a problem or if the M9 won't read Summarit lenses right now. Link to post Share on other sites More sharing options...
thrice Posted November 24, 2009 Share #3 Posted November 24, 2009 The coding on your 75 is perfectly clean? I honestly can't say what the problem would be, if the window is clean, the coding is clean and the coding is lining up, there is no reasonable explanation as to why it isn't working.

Everything is clean and brand new! I guess I will be returning this lens unless I find out this is normal from other members who have Summarit lenses on the M9.

thrice Posted November 24, 2009 Share #5 Posted November 24, 2009 Hmm I certainly don't understand it. Let us know the outcome. Link to post Share on other sites More sharing options...

As long as you can se the white marked areas it isn't the lens since it is passive and does not electrically connect to the camera. If the camera sensor area is also clean then it is likely a firmware issue assuming you have it set to auto detect the lens. Finally, it could be a hardware issue but it would be with the camera. See if it can detect any other coded lens. Link to post Share on other sites More sharing options...

The firmware is 1.002 which was preinstalled on my camera when it arrived less than a week ago. This is very frustrating. Link to post Share on other sites More sharing options...
henry joeng Posted November 24, 2009 Share #8 Posted November 24, 2009 Hi, Wonka, Have you checked that the lens detection mode is set to "automatic"? As you said, your M9 could recognize 35/2, and the 6 bits on the 75/2.5 are clear, then the M9 should be able to recognize the 75/2.5. Henry Link to post Share on other sites More sharing options...

Is there anyone here who has the 75mm Summarit on an M9 and can in fact confirm that the M9 reads it as "75/2.5?" I guess I can call Leica later today and try and get their thoughts, but I think this lens will be returned. Everything looks clean and perfect on both the lens and the camera. All I can think of is that something is slightly off with the imprinted 6 bit coding on the lens since the 35mm f/2 is read perfectly. Could the QC at Leica on Summarit lenses not rise to the level of their other more expensive lenses? Just a thought. Link to post Share on other sites More sharing options...
lars_bergquist Posted November 24, 2009 Share #10 Posted November 24, 2009 Strange. My M9 recognizes the 75mm Summarit without any problems. May I politely suggest pilot error? The old man from the Age When Only Spies Coded Link to post Share on other sites More sharing options...

I think you are right, probably the lens flange of the 75 summrit is a bit off, hence the camera sensor cannot recognize it. BTW, just read the manuel again, those newer lenses produced after 2006 can only be detected automatically by 6 bits and cannot be set manually. That's why you cannot find the 75 summarit in the list. Link to post Share on other sites More sharing options...

The old man from the Age When Only Spies Coded I will be the first to admit that I am certainly not immune from "pilot error," however, I have no idea what the error might be!

luigi bertolotti Posted November 24, 2009 Share #14 Posted November 24, 2009 I'd suggest you verify the correct position of the bit stripe of your Summarit 75 (I have one - always recognized on my M8): given that you have a coded 35/2 whose code is read, put both lenses face-down in the same angular positioning (for instance, red dot at 12 o'clock) and verify if the 2 bit stripes are in the SAME position... a mis-positioning sufficient to fool the sensor ought to be rather significant to be revealed at eyesight, I think. Btw, the well known "manual coding mask" (available on the Net) would be also useful for such test. Otherwise... I'd say it's a factory firmware-loading error which has "lost" some lens' codes...

adan Posted November 24, 2009 Share #15 Posted November 24, 2009 Just for the record, like Lars I have used a 75 Summarit on my M9 and the code was recognized - so it SHOULD be working. But there are a few weirdnesses in the lens recognition system - if I manually select my 35 f/1.4 pre-ASPH from the camera menu, ACR reads the metadata in those files as a 35 Summicron...

Wonka Posted November 25, 2009 Author Share #16 Posted November 25, 2009 For those interested, it turned out to be the lens and not the camera as I tried numerous other lenses with no problems whatsoever. Link to post Share on other sites More sharing options...
mweiner Posted November 25, 2009 Share #17 Posted November 25, 2009 I had almost the same problem except several lenses were affected and the fault turned out to be the camera. The symptoms were that 50mm summilux, 50mm cron, 75 lux, 75 cron (those that use the middle set of frame lines) showed instability with the info screen going from <correctly identified> to "uncoded'" as the camera was moved, gently bumped. The <coded>/uncoded could be more precisely toggled by moving the frame selection lever, even very minimally and gently without even affecting the framelines which were steady. The solution was to send it to Leica, New Jersey, where they made "a minor adjustment". The Leica repair contact person referred me to Mark Brady, Technical Adviser, who arranged to have UPS pickup the camera the next day and I had the camera back in less than 2 weeks which included 4 days of shipping time and 2 weekends so they actually only had the camera for about 4-5 days. It is now working perfectly in all respects as far as I can tell. Michael Link to post Share on other sites More sharing options...
mweiner Posted November 25, 2009 Share #18 Posted November 25, 2009 @ Wonka: After re-reading your post that you felt the problem was in your 50mm lens because "other lenses were not affected", I need to clarify my post because your camera may be the problem. My other lenses: 28 f2, 35 cron and lux, 90 f2 (apo and pre asph were also unaffected. Only the 50s and 75s which use the middle frame lines. When, you see the "uncoded" in the info screen, gently push the frame lever toward the lens mount (without affecting the frame set selection). Hold it there for several seconds since. If you see "uncoded" change to correct lens identification, then the problem is certainly in the camera. My theory is that lens identification depends on seven pieces of information -- the 6 marks on the lens _and_ which frame set is selected by the lens; that the frameline selection is mechanically represented in the camera in some way; and that this mechanical state is polled by the electronics at some couple of seconds intervals. My idea is that it is this "mechanical state" which is unstable. At any rate, Leica NJ found it easy to fix the problem. Link to post Share on other sites More sharing options...

Wonka, check if the bright lines are correct and clear (no missing bits of the lines) when you insert the Summarit. This is a common problem with the MATE, for instance. I also had it with the Summicron 28. On both cases, the problem was on the camera. Link to post Share on other sites More sharing options...
