[QUOTE="aroy, post: 397041, member: 16090"] Check your sensor visually. Automatic sensor cleaning will get rid of loose dust, but over the years some may be stuck and come off. Do a liquid cleaning, and that will most probably get rid of most of your problems. Another reason may be that the sensor has shifted a tiny bit, so images are not in perfect focus. To check for that do the following . Mount the fastest lense you have - say 50mm F1.8 . Set the aperture at maximum - f1.8 . Mount the camera on a tripod . Place a graduated scale ( a foot ruler is fine) at 45 degrees angle on a table or against a wall, with top away from you and bottom towards you . Adjust the tripod so that the middle of the scale is in focus, and the camera about 3 feet away . Take the shot Now check the focus on the computer. If the middle graduation; where you focused; is sharp, then all is fine. Else see how much above/below the sharp focus is. That will indicate a shift either in the sensor or the lense AF. Compensate for the shift to get sharp focus., [/QUOTE]
