Using my new 7D today to photograph birds, I noticed an annoying issue with the viewfinder. I almost always use polarizing sunglasses when I use my camera, and with the 7D, the camera shooting data along the bottom of the frame is difficult to read. I am talking about the aperture, shutter speed, exposure compensation, and other readouts below the lens view. It is the greenish-yellow illuminated info.
There are bands of darkness that move across the data readout, and they are caused by polarization artifacts in the readout. Basically, the light coming from the illuminated readout seems partially polarized. It only happens when wearing polizing sunglasses. A brighter display would help, but there seems no way to change this dislay's intensity. My 60D does not have this problem.
Has anyone else had this problem when wearing polarizing glasses? Is thre a camera fix?
Thanks!

I do like polarizing sunglasses a lot, because of their glare-reduction capability. But I could buy another pair of prescription sunglasses that do not polarize the light.
My main non-computer glasses are trifocals, but I have them made from photochromic glass or plastic, so they function s sunglasses outdoors. I don't think they polarize the light; at least I've never had the problems you describe.

All LCD's are polarized, it is the way they work. Canon must be using an LCD display with a backlight.
