There is green cast problem for some lens.

I tested several lenses

-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?
