mvravr Posted April 3, 2013 Share #1 Posted April 3, 2013 Advertisement (gone after registration) I just bought a used E55 (not 49) Tri Elmar which is not 6 bit coded. Have never owned anything but fixed lenses so far. If I have it 6 bit coded by Leica, will the camera recognize what focal length I am utilizing (not the viewfinder but the electronics)?

Advertisement Posted April 3, 2013 Posted April 3, 2013 Hi mvravr, Take a look here Leica Tri Elmar 28-35-50 and 6 bit coding. I'm sure you'll find what you were looking for!
woorob Posted April 3, 2013 Share #2 Posted April 3, 2013 I believe if six-bit coded it will recognize each of the three separate focal lengths. Quote Link to post Share on other sites More sharing options...
guidomo Posted April 3, 2013 Share #3 Posted April 3, 2013 On my E49 version it does. I believe the camera does that by virtue of the framelines that the different focal length settings pull. Quote Link to post Share on other sites More sharing options...
wosim Posted April 3, 2013 Share #4 Posted April 3, 2013 Yes, the 6-bit-code in combination with the selected focal length is recognized in the exif. I handcoded my Tri-Elmar with a Dremel and it is working perfectly. Quote Link to post Share on other sites More sharing options...
furcafe Posted April 3, 2013 Share #5 Posted April 3, 2013 The answer is yes once the lens is coded. However, even after the lens is coded, the match between the lens & body can be imperfect. See my thread here: http://www.l-camera-forum.com/leica-forum/leica-m9-forum/278248-auto-lens-detection-glitch-w-28-a.html I just bought a used E55 (not 49) Tri Elmar which is not 6 bit coded.

jdlaing Posted April 3, 2013 Share #6 Posted April 3, 2013 Mine does. It is six bit coded. 1 Quote Link to post Share on other sites More sharing options...
wlaidlaw Posted April 4, 2013 Share #7 Posted April 4, 2013 Advertisement (gone after registration) My coded 28-35-50 Tri-Elmar works nearly perfectly on the M240. The only tiny glitch and it is the same on my M9, is that the framelines tab is slightly sticky going from 28 to 50 and you have to go beyond 50 and come back again, for the frame lines to appear properly. It was set up on my M8, where the framelines change works perfectly. Wilson Quote Link to post Share on other sites More sharing options...
MarkP Posted April 4, 2013 Share #8 Posted April 4, 2013 My E49 MATE is 6-bit coded with a black pen and the camera recognises all three focal lengths. The lens recognition is determined by a combination of the lens coding and the position of the frame-line selector. Quote Link to post Share on other sites More sharing options...

I had mine (sold) fixed and coded for about $130. Quote Link to post Share on other sites More sharing options...

I had mine (sold) fixed and coded for about $130. In that the rest of it works just fine, I can live with this minor irritation. The spring was replaced when it went back to Solms for another problem but it made no difference to the frame change issue. At one point it was spending more time at Solms that it was with me, for focusing problems and wrong EXIF lengths showing up, so now that the rest is correct, I don't want to mess with it. Given the difficulties that Leica have had with this lens, I am not totally surprised that they have never reissued it, even though I think it would be a good seller. With the improved high ISO of the M240, it is going to be even more useful as a travel lens. The downside is that the increased pixels are going to show the optical weaknesses of the 28mm length even more. Mine must have been one of the last made, as it was a 30% M8 discount lens and was one of the very few made as a coded lens, rather than coded later.

algrove Posted April 11, 2013 Share #11 Posted April 11, 2013 My E49 #11625 worked great on my M9. Haven't tried it yet on my M as I am too busy having fun with R lenses. Quote Link to post Share on other sites More sharing options...
airscrew Posted June 29, 2013 Share #12 Posted June 29, 2013 I have version one (E55) I bought 1999 and it has served me well on M6TTL and M7. Now when I have finally switched to M8 this lens needs some black dots. Has anyone have his/her MATE 6-dit coded recently at Leica and is it worth of the cost? (How much?) Are there any real benefits other than have the focal length in exit data? I prefer permanent coding and have done it on my 24, 35, 75 and 90 lenses by replacing the bayonet ring with those available on ebay. It is easy to do and I haven't noticed any negative issues but on MATE this DIY fix is probably out of the question because of the frame select cam/lever.

I think you would see noticeable improvements at both 35 and especially 28mm by coding. Your lens, given its age, might well benefit from a service at Solms, which could be combined with having the coding done. There a lot of sliding sleeves and cams inside this lens and they all need to be properly lubricated. Wilson 1 Quote Link to post Share on other sites More sharing options...

I noticed some softness in the pictures, scanned and emailed the sample and they asked to send the lens in. They said that some lubricant might have evaporated sticking on lens element surface when used in warm climate (Australia, Indonesia). It came back in pristine condition at no cost and it still works well and turns smoothly but of course new CLA wouldn't do any harm. Quote Link to post Share on other sites More sharing options...

rafe Posted September 25, 2013 Share #17 Posted September 25, 2013 I have a MATE 28-35-50 E55 with 6 bit code. Everything worked fine on my M9. My M240 will not read the code for the camera to recognize the focal length and camera will not function properly with camera set to auto and auto ISO. If I use manual settings the focal length I set shows properly, but only for the focal length set. Wondering if anyone has any insight here. I also noticed that when I first snap the lens on the camera, it seems to read properly, but when I touch the shutter button, the camera stops reading the code Quote Link to post Share on other sites More sharing options...
wlaidlaw Posted September 25, 2013 Share #18 Posted September 25, 2013 Three thoughts: 1) Clean the LED sensor area with some lens cleaner - there may be some dirt/mount grease on it preventing the camera reading the code. 2) With the lens unmounted, can you check that the framelines tab is moving as you change focal length. 3) Mount a lens which brings up the 28/90 framelines a few times in case there is a bit of fluff in the framelines sensor area of the mount on the body. The MATE is working perfectly on my M240. If you press info and move the focal length ring, you can see the focal length change on the info. I assume you already have lens detection set to automatic and have not selected a different profile which has manual lens detection selected. I know occasionally I have thought on all my digital M's, why it is doing that? Only to find it is me that had changed to a different profile. Finally is the lens lock tab clicking into place properly? Wilson Quote Link to post Share on other sites More sharing options...
rafe Posted September 25, 2013 Share #19 Posted September 25, 2013 Wilson. Tried your suggestions, but no luck so far. I have 10 coded Leica lenses. Eight primes plus MATE and WATE. All eight primes register correctly. The WATE brings up only 4/16mm, no matter what focal length lens is set at. The MATE always shows as uncoded. The MATE also shows correct frame lines for all three focal lengths. Quote Link to post Share on other sites More sharing options...
01af Posted September 25, 2013 Share #20 Posted September 25, 2013 So the six code patches on your lens are misplaced. The M9 is slightly less sensitive to minor misplacement than the M, so the accuracy of the coding may be good enough for the M9 but not for the M. If the coding of your Tri-Elmar was done by Leica Camera, they should fix it under warranty. Quote Link to post Share on other sites More sharing options...
