I wanted to share a recent experience with my 50D, and see if anyone has any ideas/advice/tips for me.
Back in February, I purchased a refurbed 50D direct from Canon. I haven't had a huge number of opportunities to test it out, but after some aviation and nature stuff in my area, and about 800-900 actuations, I was fairly pleased with the body, and had had no issues. This all changed on Friday. I was credentialed media for the Langley AFB airshow, and was about an hour into the practice show when diaster struck. I had noticed that the images were becoming progressively blurrier and blurrier, at shutter speeds at which motion blur was impossible (say 1/2000 for example) and on stationary or slow taxiing aircraft. Shortly after this, I pressed the shutter, and was greeted by an awful noise, and the shutter actuating rapidly. It then siezed up and displayed a Error 20 message. I removed the battery and re-inserted it. No luck. I replaced the battery. Still no luck. I changed CF cards: no change. Tried several different lenses (all Canon) and nothing changed. At the time of the failure, I was shooting with my 100-400mm, with high speed continuous drive enabled. Any attempt to fire the shutter now is greeted by the same awful noise, rapid repetitive shutter actuation, sieze up, and Error 20 message.
Any thoughts on what this could be?
