So I'm on a conference call and it's pretty boring so I bust out the G5 and 55 Micro Nikkor and start taking some pictures of various things on my desk. I took a picture of this white car sitting on my desk and after snapping the picture noticed some very strange behavior. It's like half the frame's white balance was thrown completely off. I tried different distances to the subject, different apertures, etc and even though the location of the band of off-white balance wasn't consistently placed in the frame it was always there. My desk is shaped like an L, and if I move the car to the other part of my desk the strange color band disappears. This behavior happens with the 55 Micro Nikkor and the 14-42OIS. Only thing I could think of is the two fluorescent lights above the desk with their respective light diffusers is somehow throwing off the G5 in some way I've never seen before. Doesn't happen with the old fuji F10, my iPhone, or my Note II's cameras. I don't have an SLR with me so I can't try one of my Nikons. Move the setup anywhere else in the office and it doesn't do it. But something about being underneath the two fluorescent lights is really throwing the G5 off.
