I have a Canon 450D camera. I want to buy the 70-300 lens but it is so expensive! There is another brand "Sigma" which is the same lens but obviously not Canon but fits Canon cameras. Does anyone have any experience with Sigma lenses? It's just that £130 is much better than £395!!
I wouldn't hesitate getting a sigma lens. The only advice I have is to not get the DL model. I think there are 3 different versions of this lens and the cheapest one is crap from what I've read. I would go after the one with a red ring around the end of the lens. I think that's the DG model.
