DMJ Posted January 4, 2014 Share #1  Posted January 4, 2014 Advertisement (gone after registration) What is the advantage of 6-bit coding a Zeiss ZM lens verses just going into the camera's menu & selecting the appropriate Leica 'equivalent' ?  Is it simply the hastle of selecting it each time or is there a definite advantage?   Martin   PS. I am aware that it is not easily recognised on the M240 but that is not my question. Link to post Share on other sites More sharing options...
Advertisement Posted January 4, 2014 Posted January 4, 2014 Hi DMJ, Take a look here 6-bit coding ZM lenses. I'm sure you'll find what you were looking for!
Ecar Posted January 4, 2014 Share #2 Â Posted January 4, 2014 Convenience. You don't have to remember to change the code when swapping lenses. If you do forget (it happens to me all the time), you get the 'wrong' corrections and exif applied to the next lens. Link to post Share on other sites More sharing options...

250swb Posted January 4, 2014 Share #4 Â Posted January 4, 2014 Is it simply the hastle of selecting it each time or is there a definite advantage? . Â Yes the hassle is having to choose it each time. The definite advantage is only apparent if you want to change lenses quickly and get back into the action without trawling through the menu, but I suppose you could ask everybody to stop what they are doing while you scroll:) Of course if like many you don't give a hoot about EXIF, myself included, then don't bother.

lct Posted January 5, 2014 Share #5 Â Posted January 5, 2014 Surprised to read that there is no definite advantage aside from the hastle of selecting a corresponding Leica lens. Would ZM wides escape the red edge issue by miracle? If not, could someone explain to me why coding cannot do anything against that? Just curious.

250swb Posted January 5, 2014 Share #6 Â Posted January 5, 2014 I don't think the question was about lens corrections, but whether or not there is an advantage between manual or automatic lens recognition. I pointed out an advantage, but either way you end up with a coded lens that will bring up the correct profile. I don't obsess over it because I don't use colour, or extreme wide angles, and prefer to do any other corrections manually in any case. Nobody needs it for any lens longer then 35mm other than filling the EXIF file. Â Â Steve Link to post Share on other sites More sharing options...

JakeStone Posted January 5, 2014 Share #9 Â Posted January 5, 2014 To simplify things, if you are interested: The current Zeiss ZM lenses have a grove, which allow you code the lens with a permanent marker. Â This is straightforward handling of the topic. Â br Jacob Link to post Share on other sites More sharing options...
