Error 99 !

[Pirate Neilsouth]

Got a shot i really liked , pressed the shutter and the viewfinder dimmed and the display came up " error 99 ". I replaced the battery , turned on and off yet the viewfinder still remained dark and still the error. I tried a close up shot of anything and it worked fine , the instant i zoom right out the viewfinder goes dark and error.

:bang::bang:

Try cleaning the contacts on the lens and the body. Err99 is the catch-all "I don't know what's wrong but something is" error on canon camera's - usual source is a bad connection between lens and body.

It's the lens , i put the sigma on it zoomed in zoomed out worked perfect. This one as soon as i put the other lens on and zoom right out " Err 99 ". I've cleaned the contacts and it still does it . Also with my ear up against it , it sounds like something is grating as i rotate the lens on zoom out.

Oh well no photography for awhile :(

We used to get this on out D60/10D/20D cameras when using Sigma lenses. We had the lenses re-chipped to work with them but they still never were that reliable. Error 99 was the bane of my life for several months!!

This is the canon kit lens thats busted , the sigma works great

Which lens and which camera?
I believe that the 50d had a firmware which update which gave a few more useful errors.

Digital Rebel XTI EOS 400D

are the aperture blades stuck stopped down? as that would explain the dark viewfinder. if so set the aperture to the smallest setting (high f number) and press the dof preview button a few times and it should free them

[Pirate Neilsouth]

Cool i'll try it now


EDIT : No go and i can certainly see the blades getting stuck , the dof preview button isn't freeing them :(

Sounds like time for a lens upgrade unfortunately
