I recently shot some images using a Canon 7D with the 85mm 1.8 and anytime there was anything red or pink in the shot it just kept blowing it out. See the image for what I mean. I know it can be fixed easily in LR etc but is there any way to prevent it in camera? under-expose all shots with red? I already use the faithful picture style so the colors don't run too vibrant but is it just this lens or is it the camera? I also shot some pics today with my 50mm 1.8 and it did the same thing with pink in the shot. What am I doing wrong?
