M9 with CV15 Heliar?

[francishmt]

Anyone used the new CV15mm on the M9? I have seen some really good shots with the CV15 on an M8, but not sure how it performs on the M9 (ie. vignet, cyan drift, corner sharpness).

If you have used it on the M9, can you kindly let me know your thoughts??

On the M8 is a very good lens but on my M9 does not perform well.
It shows always a significant magenta/reddish drift localized on the left side corners.
I have seen the same problem, to a lesser extent, also on the 18mm Zeiss.
The same has been noted also by somebody else and reported on the LIF.
Cheers,

There's an issue with the M9 and many wideangle lenses (even coded Leica ones) that results in overcorrection on the left hand side of the image.

It's been discussed here: http://www.l-camera-forum.com/leica-forum/leica-m9-forum/101424-cv-15mm-versus-leica-18mm.html

Although why it always seems to the left hand side is a mystery.

There will be a new version of CornerFix (V1.3.0.0) that will be out in a few days that should be able to correct this.

Thank you Sandy, I look forward to try the new wersion of Corner Fix.
It will be nice also to understand the true reason of this strange behaviour.
