7D Question about viewfinder

It doesn't happen all the time and it doesn't affect the images and I never saw it on my old Rebel, but when I look through the viewfinder of my 7D it looks like:

not sure how to describe it
1) I am looking through a sliding glass door with the screen shut
2) it has some sort of plastic protective film over the lens (like you might use on a laptop or pda screen)

Any idea what I am talking about or what this is?? And as a disclaimer, it could very well happen on all cameras, this is not a 7D rant thread, I freaking love it!

Was the battery dead or removed? The 7D has a transmissive LCD screen and if you look through the viewfinder when the camera is not powered, it will look dark and blurry.

Damn, it might only be when I glance through it powered off! Wow, I am an IDIOT!

If it's like it all the time make sure the Diopter is dialed in.If it only happens without battery then as above.

Not many people would know this if they didn't read every 7d review there is.....

I did, and I knew this. You must have a life.
