mike prevette Posted November 29, 2006 Share #1 Posted November 29, 2006 Advertisement (gone after registration) With nothing more than a sharpie I was able to trick my M8 into thinking my Zeiss 21 was really a 50mm Leica lens. Of course this isnt for any practical purpose except to prove it's possible with little or no tools. _mike Flickr: Photos from mike@freedomfromgravity 3 Quote Link to post Share on other sites More sharing options...
Advertisement Posted November 29, 2006 Posted November 29, 2006 Hi mike prevette, Take a look here Proof of concept regarding self coding of lenses. I'm sure you'll find what you were looking for!
Jean LeBlanc Posted November 29, 2006 Share #2 Posted November 29, 2006 Well done! All we need is a database of the various codes. Quote Link to post Share on other sites More sharing options...
Bob Ross Posted November 29, 2006 Share #3 Posted November 29, 2006 Well done! All we need is a database of the various codes. I was keeping track of Mark Nortons's scans of the codings, for a while and the 21mm Elmar Asph was 000XX0. Mark or others can verify.

nemeng Posted November 29, 2006 Share #4 Posted November 29, 2006 A Sharpie... LOL! The Rat-Cunning of Leica users never ceases to amaze me :?) BTW if anyone does come up with a list of codes, I'll gladly add it to the M8 FAQ topic at: Leica FAQ - Leica M8 Digital Quote Link to post Share on other sites More sharing options...
vikasmg Posted November 29, 2006 Share #5 Posted November 29, 2006 A Sharpie... LOL! BTW if anyone does come up with a list of codes, I'll gladly add it to the M8 FAQ topic at: Leica FAQ - Leica M8 Digital Well we could start by just sending in codes of lenses we own! I'll send in my 35mm Sumicron code later this evening (morning your time). - Vikas Quote Link to post Share on other sites More sharing options...
vikasmg Posted November 29, 2006 Share #6 Posted November 29, 2006 Wonderful! Must try that on my 50mm! Incidentally, any reason for masking "M8" and the red dot?! - Vikas Quote Link to post Share on other sites More sharing options...

Incidentally, any reason for masking "M8" and the red dot?! - Vikas Street precaution – less attraction... I've done plenty of shots in the street (architectural and parks) in rather questionable areas with two M6 and a R6.2 masked. You feel somehow safer this way...

rob_x2004 Posted November 29, 2006 Share #8 Posted November 29, 2006 More the point, whats the tape over the top of the LCD screen? Um, only dots I have, which dont mean much to me at the moment.

Stan Raucher Posted November 29, 2006 Share #9 Posted November 29, 2006 The coding for many Leica lenses is shown in the images for individual lenses on the Popflash website. Stan Quote Link to post Share on other sites More sharing options...
rob_x2004 Posted November 29, 2006 Share #10 Posted November 29, 2006 Cool as Stan, I could have saved myself a minute and forty three seconds. Can I still ask what the tape is for over the LCD? Quote Link to post Share on other sites More sharing options...
sean_reid Posted November 29, 2006 Share #11 Posted November 29, 2006 Please keep up the "R&D" on homegrown coding and thanks. If we can find a solution that's more than temporary, it would be very helpful to a lot of photographers. I absolutely love it that people are trying to get this one figured out. Cheers, Sean Quote Link to post Share on other sites More sharing options...
carstenw Posted November 29, 2006 Share #12 Posted November 29, 2006 Popflash is missing a couple from the current lineup: 90/4 Macro, 90 Elmarit, Apo 90 Cron, 135/3.4, 28 Cron, 75 Lux. Can anyone help out with these codes? I am trying to collect them all. Quote Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted November 29, 2006 Share #13 Posted November 29, 2006 Carsten I have the 28mm Cron. Lovely lens and it is coded. Best way to do this is lens at camera on postion than put face down. w,b,w,b,b,w I need the 24mm 2.8 and the 35 1.4 asph. Hell i will try the sharpie. i even have colored ones.

thisaccountisdeleted Posted November 29, 2006 Share #14 Posted November 29, 2006 28 Cron. 28 summicron is 010110 35 summilux is 101110 Quote Link to post Share on other sites More sharing options...

Stan Raucher Posted November 29, 2006 Share #16 Posted November 29, 2006 Here are the codes from the Popflash photos. 0 = white (no mark with sharpie), X = black, looking at the back of the lens mount in a clockwise direction. Some lenses are missing. 21 f2.8 0XX000 24 f2.8 0XX00X TE f4.0 X0X0X0 28 f2.8 0XXX00 35 f1.4 0XXX0X 35 f2.0 0XXXX0 50 f1.0 0XXXXX 50 f1.4 X00000 50 f2.0 X0000X 50 f2.8 X000X0 75 f2.0 X00X00 90 f2.0 0XXX0X How many Sharpies can you buy for $125?

sdai Posted November 29, 2006 Share #17 Posted November 29, 2006 I suspect this thread will be quickly locked down or simply disappear because it's obviously offending the forum sponsor's business interest. Quote Link to post Share on other sites More sharing options...
sean_reid Posted November 29, 2006 Share #18 Posted November 29, 2006 I suspect this thread will be quickly locked down or simply disappear because it's obviously offending the forum sponsor's business interest. I doubt it. I would argue that it's in Leica's best interests to have this camera work with various lenses without needing to have them sent in for coding. I won't repeat my argument against a "closed system" for the M8 because I've explained it in other threads but I think that neither Leica nor the customer is well served by a closed system.

Guest guy_mancuso Posted November 29, 2006 Share #19 Posted November 29, 2006 Darn i tried the 24mm but i did it by sight , i will try again tomorrow. The nice thing is the sharpie comes off if you mess up Quote Link to post Share on other sites More sharing options...
thisaccountisdeleted Posted November 29, 2006 Share #20 Posted November 29, 2006 Here are the codes from the Popflash photos.35 f1.4 0XXX00 i don't think this is correct for the latest ASPH model (4th gen?) working clockwise, it would be 0XXX0X most of the others in this thread are counter-clockwise. we should standardize.
