I am going to continue to report the problems I am having with the 50D because it is clear from the hits I get on my blog, forums I’ve read, and posts that I have read that the 50D problems with err99 are more than ‘just a few bad bodies’. Now I will say that it has only happened to me once in maybe 150 shots, but that’s not the point….you should be able to trust hardware to either work or fail (and at the price and brand new status of the 50D I’m going with work not fail), no one wants to be on a shoot or at a place you cannot go back to and take the shot again and have a failure.
Today whilst shooting I got another err99, the interesting part was I knew it was about to happen!
I was shooting shots with high speed burst, the bursts were 3 to 4 frames only and around 15 seconds between each of the bursts. That is plenty of time for those few files to be written from the camera’s memory cache to the compact flash card.
The way I knew something was about to happen is that on the last two or three bursts that I shot the camera appeared to be getting slower between frames. Each frame exposed correctly and the shutter speed was correct but the time between each shot being taken felt like it was getting a little longer each time, and then sure enough it finally did an err99 on me.
This makes me continue to believe what I already feel, the problem is related to the writing to/from the cache and or the compact flash card. I know it’s not the card it’s self since I had been using it for at least a year on my 30D with no problems. And I know it’s not the lens as I have been using that on my 30D for at least a year and a half and have never had a problem with it.
