Camera problem

[Grifter]

Hi, just seeing if anyone knows what my problem is.

I have had a Nikon F80 for about 3 years now, and yesterday I noticed a BIG problem when I tried to use it. My view finder displays a grid of circles when I look through it. Yellow, orange, and one blue one in the center. When I zoom, they converge into one large smudge, and I can't focus at all. I'm unsure if this is a body or lens problem, and unfortunately my other lens is in another province right now, so I can only test it with my 600mm. I'm pretty confused and upset, as I take very good care of my posessions. The last time I used it, about a week ago, it was fine and it's just been sitting in my computer room on a tripod. I am the original owner.

I made a crude diagam of what I see superimposed over whatever I'm looking at, to give you an idea:



I'll be taking it in for service next week. Just wondering what the problem is, as I am pretty worried. My guess is something is out of alignment, and there is alot of refraction going on...

Thanks in advance!
