Ive checked the firmware and the only thing available was the distortion control update, I did that. I think I am going to try both of your other suggestions. I've had the camera a lil over 5 years and I really don't know what im doing with it still so there are probably a lot of setting that are wrong LOL .... As for the sensor cleaning, It automatically does that when I have the lcd screen flipped and active.
Thank you so very much for replying!!
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.,
