View finder is blurry - Pentax X90 Digital Camera

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

While looking through the viewfinder, turn the little knob at the upper-right corner of the viewfinder to adjust it.
Refer to the "Adjusting Viewfinder Clarity" subsection of the "Basic Operation" chapter of the manual (page 36 in my copy) for full details.

Well make sure you focus the camera and without leaving the shutter buton click it.Dont let the camera re focus. Also View the the image from the view finder ( digital).If not reset the camera.

You probably turned the dioptri-adjust button, next to viewfinder, by mistake. Turn it back until the viewfinder is sharp.

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.

This sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check this link for more info.

Applicable cameras include:

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

this may occuer if you are trying to expose the camera to sudden temperature changes/differences.
Eg: From your Air Conditioned Bed Room to Day Light Under Sun Light

you have to focus it using the round knob on the lens side...see it?

This is a result of Sony CCD recall issue - working with Sony for repair.
