Hello: Need comments about using wider lenses on the M9 and eventually the M240; the Biogon 21, the 18 and the expensive 15 which has it's own cross-grad center filter. I own the 21 and use Match Technical's coder, which works great. Minimal vignetting and no corner-color-shift. Plan to rent the 15 as needed for now, and possibly purchase the 18.
My concerns are more directed at the 15. When using the dedicated filter, you loose up to 2-stops, not too much of an issue outside, but when light get's low, the ISO must go up in many cases. Instead of using the filter, would the "lens vignetting" feature in Lightroom be able to handle strong vignetting of the 15. I know when you lighten the corners by 1.5 to 2 stops you will increase noise in the corners. It would be easy to apply a noise reduction brush in the corners and maybe other tweaks using a Lightroom brush, combined with the "lens vignetting" feature, and save as a preset when importing images using the 15, and to a lesser concern the 18. Any thoughts on this mindset? Anyone tried this?

Cornerfix is your solution. Create a profile, let it sort things out, then apply NR as needed. Personally I can't see extra noise from my files with a NEX7 and Zeiss 18 at 400 iso/daylight, at night you won't need to mind the vignetting much anyways.

I have neither the M9 nor the NEX7, but this might be an apples&oranges comparison, since the vignetting and colorshift will be much more pronounced on a full-frame sensor than an APS-C sensor (just based on the laws of physics).

Do the codes work with raw files?
I think only have impact on jpeg´s, or not?
My limited experience is that 21/4.5 shows a magenta wide strip at left side of frame....but the 21/4 from voigtlander doesn´t!
