I have the 450D with the 18-55 lens.

I also have a cheapish Tamron 70-300 zoom.

I also have a Minolta 70-200 lens with a Minolta to canon lens converter.

All these work great. But the minolta has to manualy focused.

I use a 2x converter which makes the 70-300 into a 180-600.

To convert these to 35mm film sizes you multiply by 1.6. So the makes my 
Tamron lens from  112mm to 960mm.
