I just noticed that when I look into the viewfinder of my F6, on the bottom part of the screen, there seems to be 2 areas that appear color distorted. It is somewhat like a faint rainbow, like oil on metal with different shades present. I don't know if I can describe it anymore accurately. Has anyone noticed this in their viewfinder, F6 or other recent Nikon SLR? The mirror is absolutely clean.
I've noticed something similar on other (non-Nikon) SLRs' i've used throughout the years. I always figured the color distortion was due to a slight "prism effect" with some optic somewhere, bending light in a funny way. Just a guess though.
Is there anything on your negatives that corresponds to the distortions? You would prefer to have a perfect view for composition and evaluation, but unless it affects your prints it is probably more of an irritation than anything else.
If you can see it , it's not on the mirror. Also if it's like a prismatic/rainbow effect, take a look at the focusing screen. Mainly the edge nearest the lens mount. Not being familiar with the F6, does it have interchangeable screens & if it does is there a fingerprint or smudge on the prism above the screen?

It does have interchangeable screens, but unlike previous F series cameras, the screen is removed through the lens mount. Replacement screens come with a special type of tweezers to remove it (as far as I know) without touching the screen.
Thanks for the replies. I'll check the viewfinder tonight when I get home. I will also have to read the manual on how to get to the screen to see if this is the cause.
