Searching for Truth on error99!
|
A Canon systems user of 20 plus years, I purchased an EOS 20D # 1320920547 on 08/05.05 from BH on 9th Ave. in NYC. Within 1-2 months of the purchase I encountered the error 99 message on a few ocassions – and each time removing and reloading the battery resolved the problem. Now after nearly a year of normal (and very careful) operation I suddenly (literally from one day to the next) notice that I cannot shoot on the program setting of my EOS 20D using the wide end of my 17-85 IS lens without getting briefly straying and failing autofocus and an error99 message and, no image after taking the shot! This phenomenon appears to be accompanied by a partial loss of control over the aperture and an overall failure of accurate metering. I can however shoot at the mid or tele end of the same lens with normal results. And when I set the camera to completely manual mode I can shoot normally. What could the explanation for this be and how best can this be permanently resolved, repaired and prevented?

clean the contacts on lens and mount. make sure you have latest firmware. be sure to format your cf cards in camera. lexar seem to be more troublesome with canon in my experience. send it in to canon if these don’t work. if under a year, warranty should cover it. or just shoot manually. a better way to shoot anyway.
it’s frustrating, i know. when i used a 10d i used to get 99 wackiness issues sometimes with certain lenses.
by the way, there is no truth with the error99 message. it’s kind of a catch all, somethings rotten in denmark code apparently.

What Jethro said. And make sure the screws on your lens mounts are as tight as they can be—on the lenses and on the body.
