I have the mk II version of this lens, and while I like it a lot the corners are not very sharp, and, on my A7s, I sometimes get magenta colour shift in the corners. I was wondering if anyone here has compared the two versions, and if it is worth my while getting the mk III version? I read that the mk III has been designed specifically for mirror less.

Version I and II are very bad at the corners/borders and not suitable for digital sensors. I own a good copy of version III today and it is very good without any smear or color shift.

However, sample variations may exist as some report. Mine is excellent, fortunately. 

Is there any difference between the voigtlander miii m mount and e mount. The e mount is 50% more in my country. Is it worth the extra money?

The optical construction is the same for E-mount and M-mount. However, the E-mount lenses transfer the Exif data to the camera, the M-mount lenses don't.

If you can live with these restrictions, go for the M-mount version when it is that much cheaper.

CV 15 III is great, I prefer the the M-version together with focus adapter or autofocus adapter (Techart).

Not just cheaper [if true], but more versatile. If you get the 

E-mount version, you still don't have an M-adapter to use 

with any other other M-mount lenses that catch your fancy.   

     

EXIF data ? YMMV but I see us Legacy-Lens-Hackers as 

being a bit Luddish .... so *obviously* the choice between 

geeky data recording [E-mount version] versus the option 

of further lens adaptations [M-mount with adapter] is clear 

as the the desert sky !

True! With a C/V close focus adapter wide angle macros are possible. And a Techart Pro AF adapter provides auto focus too. Although, with 15mm FL I can live without.

I wouldn't trade my M-lens for the E-lens.
