marcwilson Posted July 4, 2010 Share #1 Posted July 4, 2010 Advertisement (gone after registration) Hi guys, When using the older non M mount CV 21/4 and CV 15 on the M8 what is the best coding / adaptor combination on an M8? I believe the two are linked to get the best results so is it coding for the WATE + a 28/90 adaptor or some other combination? I realise the actual framelines that come up do not matter for framing of course but does it affect the corrections? Thanks, Marc Link to post Share on other sites More sharing options...

Guest V64 Posted July 5, 2010 Share #2 Posted July 5, 2010 Hi, I use an old Leica 35/135 adapter with professionally milled pits (using the JMilich template drawing), coded as a 24mm f3.8., and I find the results are I get are fine. However I do find that strong sunlight shining on the 'detector area' appears to 'leak into the coding sensor', with the result that the lens code reading is invalid., which is a bit a pain, apart from masking the area with tape/blutack, or using a finger to shade the area, I cant see how to fix. Anyone got any suggestions. Link to post Share on other sites More sharing options...
doubice Posted July 5, 2010 Share #3 Posted July 5, 2010 Hello Marc, And - welcome to the forum! There are oodles of posts on this subject. The only way any lens shorter than 24mm can be recognized by the M8 correctly is, if it activates the 28/90mm frame. That is how the system works. So - if you are using Voigtländer 15mm or 21mm LTM lenses, you have to mount them in the 28/90mm LTM to M mount adapter and code them to your liking. The 21mm Skopar can be coded as the 2.8/21mm (ASPH or non-ASPH - experiment), the 15mm Heliar as the WATE. I use the code for the 16mm setting of the WATE and am happy with it, some other users report better results with selecting the setting for the 21mm lens. Again - experiment and find what YOU are happy with - digital film is cheap…. Here is a link to a very helpful page with coding information: Leica M Lens Codes Best, Jan Link to post Share on other sites More sharing options...
