This morning I was out with the dog and the camera. I started to set the CPL for the direction that I would most likely be shooting and noticed some black specks in the view finder. After getting back to the house, I did a little detective work and tried to clean. Lens looked ok, removed it and still saw the specks. Sprayed air (bulb type blower) into the camera housing (mirror area, etc.) No change in the specks. Looked at Live view and saw no specks. Decided it must be in the view finder itself. Played with the diopter adjustment on the view finder and saw the dust in and out of focus. This points to the focus screen/viewfinder area. Correct? I don't think it is hurting the photo results, but is very annoying. I have used the bulb blower trying to move the specks etc. with no luck. Any way to clean or move the specks and to determine exactly where they are? All advice is appreciated. Thanks
