Sigma do not licence their lenses from Canon so do not have access to the latest information or firmware that Canon bodies use. This often means their lenses do not work properly with some Canon SLR bodies! Will you still buy Sigma in future?
Sigma makes their lenses with a variety of mounts. If the lens has a Canon or M42 mount then there is no problem. If it has a Minolta mount, for example, then replacing the lens will be easier and just as cheap as changing the mount. If it has Nikon mount, you can buy adapters to fit it to Canon or M42 bodies.
Sigma makes lenses with a variety of camera mounts. A lens with a Pentax mount, for example, will not fit onto a Canon camera. Assuming you get the lens with the Canon mount, then it will work on the EOS 350D with full functionality.
All after market lenses are specifically designed for a brand of camera. They are for Nikon, Cannon, Minolta etc.. They can not be cross branded just as you could not use a Nikon made lens on a Pentax.
Error 99 usually refers to a shutter error with the camera. It is most likely not your lens, but you can try it on another body just to be certain. Try PhotoTech Repair Service, in NYC. They are an authorized service facility for Canon cameras. Also if you join they're facebook discount, they will give you 10% off the repair.
Here is the link to the facebook page, it has everything you need to send in your camera.
This is what the people at the canon tech support say to do for error 99
read this!! :)
The guy at tech support listened and then told me that the lens contacts were dirty and to get a pencil with an eraser on the end, just a regular old pencil with a red rubber eraser. Detach the lens from the camera, hold it so that the lens’ gold contacts are pointing down and lightly erase their exposed surface, cleaning them of any hand oil that might have gotten on them.
Do the same thing with the gold contacts inside the camera body. This is a bit harder but it’s doable: just hold camera so lens opening points down so no gunk falls in. Erase lightly. I used a lens cloth and dabbed at the contacts rather than blow them so as not to blow the erasings inside the camera.
I did this to each of my three lenses just to be sure. Lo and behold, it worked
hope this works for you!!!! have a nice day!! :) :)

Greetings! Answer to your question is, ‘Yes’ we can. Use Sigma
FD lenses. As we know Canon AV-1 has electronically controlled
AE (Automatic Exposure) & has a Canon Breech-lock lens mount. Original generation of FD lenses featured a silver
locking ring at the base. Only that locking ring turns to lock the lens to the
camera body; the lens body remains still. In the newer lens system which was introduced with
this camera, the user has to line up the red dot on the lens, with the red dot
on the camera and simply turned the whole lens clockwise until it clicked into
place. Note: FD-mount cameras could use FL lenses in
stop-down metering mode. Thank you & have a nice day.
Simga makes lenses to fit several different makes of camera bodies including Canon and Nikon. I'm assuming your Sigma lens has a Nikon mount, if so there are some adapters, but they may not work like you want - not all functions may work properly thru the adapter. For best results you should return or sell the lens and get one with the Canon mount.
