I wonder if this lens from Tamron:
Tamron SP AF200-500MM F/5-6.3 Di LD
is compatible with Canon 450D.

Also yesterday I was supposed to buy a 2nd hand Sigma 12-24mm F4.5-5.6 X DG ASPHERICAL HSM, when the seller let me tried it with Canon 450D, it was not compatible with the camera, is the lens too advance for 450D?

What is the quality of this Tamron lens:
Tamron AF11-18mmDi-II F4.5-5.6 (A13)

Thank you for your help.

Tamron and Sigma lens have different mounts, of coz they should have Canon mount. You have to make sure getting Canon mount.

For wide angle lens, please consider EF@ 10-22. Super Quality!
It has a Super UD lens inside, quality close to Canon L lens.

Can anyone suggest which lens I should get if I want a wide angle lens with f/ 2.8?
