I've only had my 50D for aobut 3 months and have put on about 2600 shots. Two days ago I started getting error 99, which I had never had before on this camera or on my previous XT. I was using my siggy 105 and did all the things - turn off and on, took the battery out, switched from my 3rd party back to my canon, etc. It happened about 5 times - take a few shots, error, take a few more - error.
So today I updated the firmware from 1.0.3 to the new 1.0.7. I'm also using a canon lens today - my 70-300 DO. And now I'm getting ERROR 30! WTH is that? The only things I can find on it refer tothe 5D, NOT the 50D. What is error 30, and what should I do??
