error99 on Canon EOS 350D

i keep getting this ------error99.on my eos350d----any help with it please

I think its a "general" or unexpected error. Have you tried all the suggestions in your manual?

Try cleaning the electrical contacts on the lens and on the throat of the camera. A small pencil eraser is good for this.

Does this just happen with one particular lens or with all lens?

Sell it and get a Nikon.

Now why would he want to downgrade

Straight from the web. Just google the error message.

Well done Bob!
Lets hope that works for you Tony. Let us know how you get on.

thankyou for reply's,
this only happens when the 70/300 is fully extended say for macro,if i switch camera off and then back on bring the lense back a fraction it will work,,,,,,,,i have tried the contacts on the lense and camera body,removed and replaced battery,and removed memory card,and tried to reformat card,,,,,,,,,,,still not good :{

If it doesn't happen with other lenses then the problem possibly lies within the lens itself. If you know of someone else that has a Canon camera try using that lens on theirs, this would prove it down to being a fault within the lens if it happened on another camera.
With the lens fully extended it must cause some sort of disconnection which would mean a repair job..
You say it happens in macro mode but you don't say if it happens in normal mode, it could be down to a faulty macro switch in the lens.

Just had a thought, is their any movement where the lens is connected to the camera, say up/down movement? The slightest play on the connection point between camera and lens could result in the error showing up. This needs to be a really firm connection without play.

If trying to do it with the extn rings the fault could be with them.
