color shift due to lens

tonight i shot some pics at a high school football game. the uniforms were bright blue shirts and white everything else. i could swear that what i saw with the naked eye was much cooler in K than what i saw through the viewfinder (10D with 70-200mm 2.8 lens). is it possible for a lens to cast color? i'm not talking in the image, just through the viewfinder. or, could it have been psychological, or simply the whole view-finder>lens system causing that cast. i just never noticed this before. interestingly enough, the develops of the raw files had to have their color temp adjusted, cooler. granted, there are LOTS of different color temps to the lights that were lighting the field. you know, some bulbs are older or different altogether - greenish, reddish etc... differing intensity.

anyway, so is that something i've just never noticed before - lens color cast?

i guess i found an answer to my question - in Capture1 4, there's a lens cast calibration function. so there you have it. i just never noticed it so pronounced.

What you are most likely having an issue is with the white balance.... lens AF calibration has nothing to do with this.

Yes, some lenses have a color cast and some lenses will even shift various shades more than others. Custom white balance can be set using a grey card or you can post-process it out.

If you're having issues under certain lighting, shoot RAW and you can cycle through white balance modes in DPP or set the white balance to a custom setting.
