I am supposed to be at a function being the tog! Camera comes up with err 99, shooting not possible, switch off or reinstall battery. Tried all of that and nothing works.
Help quick please!

Have you tried removing the lens and cleaning the contacts?
 
Have you tried using a different lens?
Err99 is a generic error code which can mean the camera isn't talking to the lens or many other things. Sadly it can also mean your shutter has failed, that was my experience with a 1d mkIII.
I think you need to find someone local you can scrounge a camera off
 
Try a different lens...

Recharged battery.....

Different Cf card.....

most likely as GarynLea says the contacts between lens and body, use a pencil eraser.
 
i really do hope you can get this fixed quick, but i guess its why a second body comes in handy..... hope you get it sorted pal...
 
Yes I tried all of those things! I changed lens as I recently bought a s/h 24-70L and wondered if it was that. Put back my sig 17-70 on and it worked! For 10 shots and then went back to err99.
Tried an eraser as well, getting bad vibes!! Will give it all a going over in the morning, if not I will have to get it to a camera shop.

Thanks for the replies.

Just got home after a pretty awful evening. Took the battery grip off and just put a battery in the camera, appears fine!! Why would poor contacts give a 99 reading I wonder?

Err99 is basically the blue screen of death.
It's the camera going "nah i don't like it"
and you ask what, and your camera goes "nah just don't like it".

it can mean any manner of things. usually all it is is that your camera isn't connected correctly to one of the external things, i.e. flashgun, battery grip, battery, memory card, lens, etc. sometimes it means that something internal is, shall we say, fubar.

Yes can do, one of the things to try - as mentioned above - is to try the batteries directly in the camera if you are using a grip, so if this solves the problem (and I hope it does for you) you know the error is occuring re the grip. You've tried virtually everything else I could possibly suggest, hope you manage to sort the problem :thumbs:
 
Tried camera again this am with just a battery works fine, must be the grip then? Put the grip on, works perfect! I think I will a] put it for a service and be get a back up body!

Cheers,

Duncan
