Problem with "inherited" macro lens

My Mum has passed quite a bit of gear onto me, including a Sigma macro lens (50mm 1:2.8). I have attached it to the body of my Canon EOS 30D, it fires and even autofocuses and I get readings re aperture and speed but then when I take the picture, I get a message on the screen saying " Error: Err 99 shooting is not possible. Turn the power switch to and again or reinstall the battery".

Is this lens compatible with the Canon EOS 30D? There is no indication otherwise in the instructions. Is it a bad contact? If the lens is damaged, is it worth repairing?

Any advice welcomed.

Cheers Smile

Sam

Been doing some surfing on this lens and it seem to be v good quality for the money and several people are using it on Canons DSLRs...................

Err 99 is Canon's code that covers a multitude of possible problems. First thing is to clean the lens contacts and try it again and also try the lens on another camera. If still no joy, hit it with a lightweight hammer.

Excellent advice for a luddite. Any particular make of hammer?

It's possible you'll need to have it re-chipped before it'll function properly, otherwise the only way it'll be usable is at maximum aperture.

I've just rattled off a mail to SIGMA asking about rechipping. Awaiting feedback.

Thanks GlennH

Most people prefer a wood shafted Vaughan Upholstery but as its a Sigma....use any old Draper Claw.

If this was a Nikon, you would need to set the lens aperture ring to F22 (or smallest) Otherwise you get an error message.

However since it's a Canon I suggest you follow the most recent advice.

Have contacted Sigma and been told " due to the age of the lens we do not have spares available to make it functional with newer digital cameras". I guess I can put it up for sale or something.

You could try an independent repairer - have a look in your local yellow pages or contact a local photographic society.

why not try use it with an extension tube that has no pins so you can use it on manual setting, does the lens have a manual aperture ring, just a thought.
