M10-P and non 6-bit 50 Summicron

Hello,

Other than having the lens info in the EXIF data, is there any reason I need a 50 Summicron to be 6-bit coded to use with my M10-P? I have a rigid that seems to work fine if I forget to change it from my V4 35 Summicron. 

I am looking to get a V5 50 Summicron and there seem to be a lot more non coded ones for reasonable prices VS coded ones.

Just making double sure before I buy a non-coded one.

No, there really is no reason for a 50 to be 6 bit coded as the angle of view is not wide enough to need digital edge color correction from color smearing.

The V5 50/2 is a wonderful lens but if you already have a rigid, then I would suggest you consider the Zeiss 50 Planar for a LOT less money and be able to keep your rigid for character and the Zeiss for "modern".

Thanks, that is what I thought. I had the Planar before and it is indeed a great lens but I wished it did not have a bright chrome front piece and it is a but wider than 50mm so I am going for al all black V5 Summicron. The Rigid lives on my M3 so of course that stays.

M lenses 6-bit coded by Leica are calibrated for digital. May prevent  back or front focusing but won't fix focus shift, in my experience at least. That of Summicron 50/2 v4 & v5 is not huge though.

I found a mint 6-bit for an average price with a great warranty, I am all set now.

Generally true but not necessarily so.  I had the 28/2.8 Elmarit asph v1 that was released at the same time as the M8 in 2006 and it was 6-bit coded but 'too early' to be calibrated for digital because no one yet understood that digital calibration was needed.

No.
