There is green cast problem for some lens.

I tested several lenses

No green cast problem:

-tokina 11-16 f2.8 AT-X pro

-canon 16-35 f2.8II

-canon 135 f2 L

-canon 50 f1.8 stm

-canon 24 f1.4LII

-tamron 24-70 G2

Have green cast problem:

-canon 85 f1.2L II

-tamron 17-35mm F/2.8-4 Di OSD (Model A037)

-canon 50 f1.2L

-tamron 45 f1.8 VC

I post my shots a the comment of my post in this page https://www.facebook.com/groups/SigmaClubThailand/

Thanks for reporting,

1. Is there any EXIF info transfered to the X3F file?

2. Did you consider to edit the lens entry in the custom EXIF file to trigger the color cast correction in SPP for pictures taken with lens where you oberserve the cast?

3, Do have a comparison of resolution of the Tokina 2.8/11-16 in H-mode to the Sigma 4.5-5.6/8-16mm in APS-C mode or crop mode?

Lens exif info (focal length, F value) are in raw and jpg file

The lens that I mention have green cast problem, I'm not so expert in post production, I can't correct color.

Now I can't compare because of my 8-16 in SA mount. From my feeling tokina give brighter picture and a little bit sharper.
