Thanks everyone for your insight on this problem. Here is an update: 1) I cannot reproduce the problem 2) Where I was shooting there were 4 windows with blinds (opened a little). 3) I had 50/1.4 lens on it with a filter. 4) My assumption is that the light from the blinds is falling on the filter and in turn the filter just redirected the reflection to the subject. 5) Not sure why it would look red though. By the way, 1) I did not shoot through any windows 2) There is no flash attached to the camera 3) There is no else except for me shooting. Thanks everyone for your valuable insight and this is only my explanation. Anyone has a better explanation feel free to post it. I am now convinced that its not a problem with the camera. thanks, srinivasa regeti
