...All was good until last week when I fired up the camera for the WCHA Final Five college hockey games in St. Paul, MN. The top display was flashing "F." I tried to turn the aperture ring and reset it to the "A," but nothing worked. I thought, well I am not going to be able to take any pictures since I cant get it to work. Then I remembered in the menu that you can turn off the aperture setting to allow it to take pictures. I turned it off and it worked fine.
Is there something wrong with my lens, camera, or both? I mean it works fine but why did it work for a little bit but started acting up after a few days where I had to turn that setting off just to get it to work properly?
Chances are that the lens aperture ring was moved from the A setting (possibly when mounting and dismounting it). Some lenses are difficult to get reset to A. You need to NOT hold down the button and move the ring to the smallest f-stop (probably 22 or 32). Then depress the button and rotate the ring fully to the A setting. There is a little contact that pops out to tell the camera that the lens is in the A position. It's possible that the contact got stuck, or the electrical contacts on the camera or lens are dirty or didn't seat properly.
Clean the electrical contacts, check the operation of the aperture ring, and be sure the little contact on the lens is moving as it should. Chances are you can get everything working as it should.
