jamesk8752 Posted February 5, 2011 Share #1 Posted February 5, 2011 Advertisement (gone after registration) I know, I know, these lenses really don't need to be 6-bit coded for use on an M8.2, but I'd like to do it anyway so I have the (approximate) focal length encoded in the EXIF files. Carsten's list of 6-bit codes has no recommendations for coding the Zeiss 85mm lenses. For lack of better information I used the code for the Macro-Elmar-M 90mm f/4 on my Tele-Tessar ZM 85 f4 and the code for the Apo-Summicron-M 90mm f/2 ASPH on my Sonnar ZM 85mm f2. The codes are recognized by my M8.2, but are they the best choices? Your suggestions would be welcome. Regards, Jim Link to post Share on other sites More sharing options...

lars_bergquist Posted February 5, 2011 Share #2 Posted February 5, 2011 I would say that for any lens longer than 50mm, it does not matter the least exactly what code you use, because it won't make any damn difference to the picture.

AGeoJO Posted February 5, 2011 Share #3 Posted February 5, 2011 I agree with Lars, lens correction-wise it doesn't make much difference, if any, how this lens is coded. I recently purchased this lens and I have been quite pleased with it, very sharp in the center with pleasant bokeh. I am not saying that it is better than my 90mm Apo ASPH but it is as good and for portraits using my M9, I prefer the Zeiss Sonnar 85mm f/2.0 lens over my 90mm AA. Mine doesn't have the recessed groove my Sharpie coding is smeared all over so, I stopped doing that. If I remember to change the setting on the camera, I put the setting of the 90mm Summicron non-AA for me to differentiate the EXIF. Link to post Share on other sites More sharing options...

I will use the 90 APO ASPH code, since I already have the older Summicron 90 pre-AA and it's been hard-coded by DAG. Thanks! Regards, Jim Link to post Share on other sites More sharing options...
