My camera is only a couple of months old.  I have taken hundreds of pictures with it and I usually shoot on shutter priority setting.  I took my camera to a wildlife park yesterday.  It was clear, sunny, warm, no clouds.  At least half of the pictures were blurry. I expect a few but that many? And 6 times the camera took black pictures just like I was trying to shoot at night with no flash. The SDHC card is probably a couple of months old. I format it usually after each use.  The battery was fully charged.  Any ideas? Do you think my camera is getting ready to break? Thank you.

Thank you for your replies.  The switch on the lens is still on autofocus.  Of course I noticed the pictures were black as soon as I took them. I was just wondering if anyone knew why there were so many in one day since I have never had a camera do this before.  I know aperture affects the picture and how much of the picture is in focus but I am saying nothing was in focus.  I can't post an out of focus picture because I deleted all of them before I thought about this forum. Shutter speed was 1/500, aperture ranged from 6.3 - 10, ISO was 100. It was a bright sunny day and the animals were out in the sunshine. Thanks. Beginning to sound like a chance happening and I will have to wait and see if it ever happens again to see where to go from there. Thank you.

OK under those conditions you just specified, your lens had to be set or stuck in the minumin focus distance. That would explain completely OFF pictures. The black extremely under exposed is still a mystery.
