.....So far I love my lens, but I encountered something strange.... I have been taking some portrait shots for a campaign. The studio is way too tiny (it was a studio for greenscreen videoproduction), so I have been forced to go quite wide. I thought I would give the 35 a try ... As you can see in the enclosed shot I got a weird greenish cast on her chin and below. I sent it back for service just to receive it back being told that this was probably an artifact of the light bouncing back thus creating this effect.. A kind of flare..?....
Any thoughts on this?

... sorry to say this but i have some thoughts (we should be worried about this fact alone:-)... and yes, could be they are right on - do you have a weird greenish or slightly dirty coloured floor or something reflecting from below?
- the place does look somewhat high key and with the darker face indirectly lit - i've found when shooting in bright sandy situations with the body beautiful somewhat shaded and against the sun that yellow (from the sand) is often reflected onto the underneath bits (under the chin, bare legs and such) and blue (from the sky) is reflected onto the up above bits (shaded shoulders and arms) … and indeed previous brands (who's names i can no longer mention:-) not so much sigma as such, and i always thought it more the sensor than the lens) seemed at that time to be quite prone to this funny colour business (not so funny when doing the post however requiring colour brush skin touchups with masks) … but i'm only a part timer from the great outdoors and could be quite wrong …
