[QUOTE="WayneF, post: 352195, member: 12496"] Hard to believe the lens changing from f/2 to f/2.2 could do anything like that. Then the first thing to do would be to compare the White Balance between the two cameras. You've never said what the White Balance is... do you know? Say the words. :) I'm not sure it is any normal WB though. Daylight WB under incandescent lights would be more orange, somewhat yellowish, not Red. Your image Red and Blue channels are about alike, but green is well down, a couple of stops, surprisingly so. Looks very abnormal. Seems more likely you've done something like Preset White Balance, and got it all mixed up. Try the two button Reset, D7100 manual page 131. It seems a good bet to fix it. [/QUOTE]
