Johnny_Johnson Posted January 20, 2010 Share #1 Posted January 20, 2010 Advertisement (gone after registration) Hi Folks, I'm ready to permanently six-bit code a Minolta Rokkor 4/90mm lens and hope that I can get some advice from the more experienced members of the forum. I would like to code it as a Tele-Elmarit-M 2.8/90mm because that only requires the milling of one slot in the flange. I've already tried that code with a permanet marker and the camera is picking it up and writing the focal length to the EXIF data. My question is - will coding the f4 lens as f2.8 cause the in-camera processing to make any undesirable modifications to the DNG file? My first thought is that it won't on a longer focal length lens like a 90mm but thought I'd best ask before proceeding. Thanks, Johnny Link to post Share on other sites More sharing options...

epand56 Posted January 20, 2010 Share #3 Posted January 20, 2010 I have the same from Elmar-C and it is a superb lens even not coded. Link to post Share on other sites More sharing options...
Johnny_Johnson Posted January 21, 2010 Author Share #4 Posted January 21, 2010 The only reason that I'd like to code the lens is to capture the focal length in the EXIF data. Link to post Share on other sites More sharing options...
