Originally posted by Billium28 I was taking some pictures this afternoon with my brand new (less than 24 hours old) K-x. I noticed strange looking specs in viewfinder. They are fine dusty powder looking dots. If you look hard they seem to form rings going outward from center. I tried looking out a bright window, with and without my glasses, and at a white wall. Still show up, dusted off the lense, and then the viewfinder glass and no change. Until I moved to wide angle, 18mm, they disappeared, or to be more exact, they went out of focus enough to disappear. At tele they reappear, and as you move down then lense they faintly fade away.
I never had the lense off without the covers for more than 3 seconds. And when its not in use it has the lense cap on. I dont see the specs in the pictures zoomed in. I did the camera sensor shake clean still no change.
They are not distracting enough for me not to use it but I find it odd, I dont remember them being there last night when I started using it out of the box.
Any ideas?
Just a couple of notes here,
- dust on the viewing screen will always be at the same focus regardless of lens attached, therefore it is probably NOT on the viewing screen
- cleaning the sensor will not impact dust on the viewing screen or any where else in the optical path when looking through the viewfinder because the sensor is NOT involved in the viewfinder image
I suspect if the dust moves in and out of focus it is either on the mirror, or the rear element of the lens,
