Camera-fix for DSLR"s with removeable-lenses.
Problem: the auto-focus was malf'ed, would only initiate focus on the wide-open aperture settings. (Lens on this particular camera have focus-motors in the lens-body, Pentax)

Solution:...Clean contact areas of the lens attachment plate, and that of the camera-body using a small amount of isopropyl-alcohol (Rubbing alcohol) on a Q-tip, and removing the alcohol with a microFiber cloth.

I ordinarily use only a DRY soft artist's brush to migrate dust particles off the sensor's surface. Some pollen's will adhere, and may have to be removed with wet-solution cleaners.
This vid shows a clear view of a Canon's sensor being cleaned.
