All of a sudden everything is out of focus and very blurry, pictures and even through the view finder. we took a few pics tht turned out normal, set the camera down picked it up about 5-10 minutes later and it was blurry.

I had a problem similar to this. Try taking off your glasses or removing your contacts and try again. Best of luck.

Your camera is equipped with a optical diopter that will allow you to adjust the optics in the viewfinder to your eye. meaning bringing everything into focus as it should. The way I use this (set it) is to let the camera auto focus on a subject and then turn the diopter until I see the subject clearly.
It really helps if the subject is about 12 feet away (get it real sharp) and the camera is mounted on a tripod. Once set I put a little dot of paper white out on the diopter adjustment knob so if it gets turned I know and can quickly return it to the correct spot. I'm including a diagram where this adjustment knob is on your camera, have fun.

Adjust view finder focus as you will see setting there, to view correct focus in view finder itself.
Camera is just fine because it is taking good focus pictures.

Next to the viewfinder ther is a diopter adjustment so you can change the focus in the viewfinder. this is so if you need glasses the camera can be set for you. Start by focusing the camera on something, then slide to turn the diopter adjustment until it looks sharp and try not to bump it.

you have adjust diaptor wheel acoording to your eye setting. adjust your camera according to this sujetion you want get blurry picture.
you can get this diaptor wheel next to view finder.

Ok. On your viewfinder, there might be a round dial. Turn it to adjust focus. Otherwise, sometimes viewfinders are like that... blurry, especially electronic.

jbenjack,
The D80 has a lot more settings to deal with and depending on the lens the depth of field may explain the blurry background (that is desired effect on a portrait) The view finder on the D80 is for composing the shot and has read outs for the settings. The LCD on the back is for playback and the menus, it doesn't work like a live view of what's being taken (on some newer and more expensive DSLRs it does preview on the big LCD) on smaller point & Shoot cameras that don't have a viewfinder they use the LCD as the viewfinder, does that make sense? If she has the manual you may want to faniliarize yourself with some of the features, start out on one at a time for the different modes so they make more sense, you can really appriciate the camera after that and respect what pro photographers do. The D80 is not a cheap camera and I personally know a couple of professionals that use it among their cameras. (lots of different lenses that cost many time more than the camera body) Have fun with it, and if you get into it you will find you can take some fantastic photos with it. Can you tell that I like that camera?

You need to let the camera auto-focus time to do its job. Press and hold the shutter button half way until the white square in the LCD display (or LED light next to the view finder) turns green, then press the button all the way down for the camera to take the picture.

You probably got some condensation on the lens from going in and outside. You should be able to go to a Wolf Camera or similar store and have it cleaned.
