I went out early Sunday morning to shoot some pictures of a waterfall. After climbing down in the darkness with my backpack, camera, and tripod I took a series of exposures (shooting large Raw and small J-Peg) and after the third exposure I saw the busy signal, unusual for just three exposures. I waited and then looked at my watch and waited another 5 minutes and it was still "busy"? I finally turned the camera off and then saw a picture of a spinning disc and a message saying that it was still recording? I also removed the batteries when I switched cards, left the power OFF for ten seconds with the batteries out. I hoped it was a bad card and put in another card, this time I got several series of exposure before it did the same thing? Figured something was broken and gave up in discust, climbed back up the hill from the bottom of the falls and stoped at the top of the trail, set my gear down, pulled out the card and put in another, this time I formatted the card (though I always format my cards in camera as soon as I download), after formatting the camera seemed to be working again. I went BACK DOWN to try and get a few more exposures and darned if after I got back down there I had the same problem????? I gave up and trewkked home figuring my camera was going on a trip to Canon for repairs. Downlooaded the images I did get and there were twqo that had a purple line across two of the images? and several had a purple cast to the images? After dumong the photos, I put the cards back in the camera, formated the cards, and took a bunch of pictures off the deck, snapping them as fast as the camera allowed, and NO problem.....? Has anyone had a similar problem? I am now torn as what to do? Send it in for a checkup? Wait for it to happen again? Am planning on a trip to the coast to do a weekend of shotting lighthouses with a group, do not want this to happen then. HELP....
