artur5 Posted January 9, 2007 Share #21 Posted January 9, 2007 Advertisement (gone after registration) Well, it's going to be a chewy problem if that's the case. Even if Zeiss sells us the mount, I would not be so enterprizing as to unscrew the mount of the lens. Have you done this before without affecting the precision of the lens mount? I swapped with success the bayonet rings of my ZM35 and ZM21, just for trying if they were the same.( and they were). Those rings are just fixed to the lens body with 4 screws and, at least on my lenses, only reasonably tightened, not glued. You need a good screwdriver of the correct size and shape, taking care not to damage the screwhead. The bayonet ring fits very smoothly and precisely over the lens body and if you align with care the screwholes of the two parts, you cannot ruin anything. There are no springs, levers or moving parts underneath the bayonet ring, it's only this: a ring screwed to the lens body. Of course I'm not encouraging anybody to dismantle his/her lenses... I'm only thinking that Zeiss, if willing, might easily release a new version of the ZM25 bringing 24/35 lines on the M8, instead of 28/90 like now and a ZM21 with 28/90 instead of 50/75. They could do it at zero cost and also offer the ring change to the actual owners at a reasonable price, like Leica does with lens coding. Link to post Share on other sites More sharing options...

atufte Posted January 10, 2007 Share #22 Posted January 10, 2007 000110 in my table is the IV (4th gen) 35/2, pre-asph. Ah sorry! I am mixing up posts. That is already the one you tried. Well, this is even weirder. All 35/2 lenses seem to report f/1.4. Out of curiousity, do you feel like posting a picture of your coding attempt? Here's a picture of my Summicron 35/2 with the "sharpie coding"... Welcome, dear visitor!

arthury Posted January 11, 2007 Author Share #23 Posted January 11, 2007 As of today, all of my Leica-M lenses are coded with the caveat being the 35mm 'cron showing up like 'lux. I still cannot code my 21mm ZM lens successfully. Did anyone code a ZM lens successfully? Link to post Share on other sites More sharing options...

thisaccountisdeleted Posted January 11, 2007 Share #25 Posted January 11, 2007 I still cannot code my 21mm ZM lens successfully. Did anyone code a ZM lens successfully? i haven't.. but just a suggestion, have you tried it in all three frameline positions? what frameline does the leica 21mm bring up?

jaapv Posted January 12, 2007 Share #26 Posted January 12, 2007 As of today, all of my Leica-M lenses are coded with the caveat being the 35mm 'cron showing up like 'lux. I still cannot code my 21mm ZM lens successfully. Did anyone code a ZM lens successfully? Yes. I coded it for 21 mm, no problem. But I painted the screwhole with Tippex, as the screw apparently got seen as black. The camera will only accept the coding if you push the framline lever to bring up the correct framelines (all the way to the lens). Clearly the coding is linked to the frameline-selector, as it must be to recognize the Tri-Elmar long. This, btw brings the number of possible codes up to 192. Additionaly, if one wishes to switch off the recognition of a coded lens , for instance to use the natural vignetting, it suffices to move the frameselector lever. No need to go into the menu for a single shot. Link to post Share on other sites More sharing options...
sean_reid Posted January 12, 2007 Share #27 Posted January 12, 2007 Advertisement (gone after registration) One lens that's a real pain to code is the 21mm Zeiss ZM. There's a mount screw right on where the white-dot is supposed to be. I think it is not as reflective as the lens mount. I read that someone else painted the screw with white-out. Anyone else succeeded with 21mm ZM ? Yup, but you must remember to hold the frame line selector in the right position. Cheers, Sean Link to post Share on other sites More sharing options...
arthury Posted January 12, 2007 Author Share #28 Posted January 12, 2007 I confirmed it. Got it, guys! I held the frameline selector towards the lens and it worked! Thanks very much. Looks like that outer frameline is a little smaller than what the lens can do. But, it worked and I'm happy. Good tips, guys! Link to post Share on other sites More sharing options...

Hi Arthur & Jaapv Could you kindly post up a picture of your self-coded ZM21? Fine permanant sharpie used? I'm preparing to self-code mine as well. Also interesting me - is the self-coded small black squares going to fade or dirting the M8 body mount after several lens change?

sean_reid Posted February 6, 2007 Share #31 Posted February 6, 2007 The trouble with this lens, that I have too- is also with the frame lines. It brings the 50/75 pair instead of the 28/90 as the Leica Elmarit 21/.28 does. So, unless you replace the bayonet ring of the ZM 21 with another one that brings 28/90 lines, you won't get the lens properly recognized as a Leica 21/2.8, even if the screw issue is fixed with white paint or something.As I've already written on the forum, I tried to buy from Zeiss a bayonet ring for the ZM 28/.2.8. That ring mounted on a ZM 21/2.8, would bring 28/90 lines, but Zeiss didn't answer my request at all. And before someone asks, yes, all Cosina-buil ZM share the same bayonet ring, only change is the keying flange of course. If you want to know if the self pàinted code works on the ZM21, try to paint the code for a 50 or 75 Leica lens, just for testing purposes, and see if the M8 recognizes the lens. I would do it myself but I haven't the camera yet.. Actually, to trigger that code one just needs to code the lens and then hold the frame line selector in the 28/90 position. I've done that throughout my testing of the ZM 21/2.8. Longer term, the bayonet swap is the way to go. Edit: Sorry, looks like I came late to this party.

I think it is not as reflective as the lens mount. I read that someone else painted the screw with white-out. Anyone else succeeded with 21mm ZM ? No - I cannot get my M8 to recognise there is a coded lens mounted at all with either the ZM 35 or 21mm lenses using the felt tip marker method. I have not used a white marker for the zero pits as I had assumed that the silver of the mount would be sufficiently reflective - was this my mistake? I had assumed after I turned on lens detection that I might well get the wrong lens and need to fine tune but was surprised to get no lens.

carstenw Posted February 6, 2007 Share #34 Posted February 6, 2007 Wilson, either the lens detection option in the menus is not on, or you must have coded in the wrong places, either with an offset, or maybe backwards. Check all your steps really carefully, and if nothing helps, perhaps post a picture. Link to post Share on other sites More sharing options...

Check all your steps really carefully, and if nothing helps, perhaps post a picture. Carsten, I started with the 35 Biogon as it is very easy to code. White, four blacks and then white (ASPH 35 Summicron). I used the template and it looks like the markings are in the right place relative to the sensors. I did of course, turn on lens detection, with a little trepidation given the warnings in the manual. Took a photo and looked at an EXIF - nothing. I will have a go at putting the marks on more carefully. One problem I might have is that all the markers I have found in the UK, have a rather shiny finish when dry. I will go to my local art shop today and see it they have something that dries matt. Sharpies are not sold in the UK. Wilson Link to post Share on other sites More sharing options...

steich Posted February 6, 2007 Share #37 Posted February 6, 2007 Hi, after using a lot of the German equivalent of Sharpies (we call them "Edding", I hope it doesn´t mean anything annoying in colloquial English ;-)) ) --- and a lot of alcoholised Qtips to remove the marks from the wrong places, I quit. Could it be that Sharpies leave a matte colour spot and Eddings don´t? Anybody here who has used "German" markers successfully? My self-coding-workflow was: - print the template (with the grey part 1 inch long) - cut out the center and two tiny marks needed for my 2/35 - align it on the lens back - mark the two spots through the template with an Edding - turn on the camera - switch "lens detection" to "on". - take a picture - press "play" and "info" - see anything on the display but the lens type.... :-(((( What could I have done wrong? No, I haven´t tested yet if my M8 recognises coded lenses at all (I haven´t got one yet). I´ll go and try at a Leica dealer when I come to town the next time.

I am off to the art shop this afternoon to see what else I can find in the way of marker pens. Wilson Link to post Share on other sites More sharing options...
carstenw Posted February 6, 2007 Share #39 Posted February 6, 2007 I have just tried to mark my 35/2 Asph with a Staedtler permanent marker, and it did not work either. I am also looking for something else. Just in case the template was off, which someone hinted at once, I didn't use it, but went back to first principles, putting a piece of tape on the camera around the mount, marking the sensor locations, attaching a piece of tape on the lens, putting it on the camera, transferring the sensor locations, and marking it like that. I will now try an IDenti-pen. Link to post Share on other sites More sharing options...
arthury Posted February 6, 2007 Author Share #40 Posted February 6, 2007 You guys are cracking me up with the Sharpie thingy ... Sharpie is just a common brand here in the US: there's no magic here. Any pen that has all these characteristics should work: felt tip (fine, if possible) black ink permanent ink Even though it is permanent, they do come off quite easily if you take a piece of cotton wool and rub it off. Don't use tissue paper or paper towel or you will leave lots of lints. And, always blow the lens clean with a Giotto rocket before mount the lens back on.
