The Sigma 70-300mm Super APO DG Lens is a very reasonable zoom lens for the beginner to intermediate photographer. The product comes with a lens hood and case for its price, which makes it very good value, much better than a similar Canon lens for example which costs more, comes on its own, and probably charges you about £20 for the rubbish bit of plastic that it takes to make a lens hood.

The Sigma also seems to get a little confused with the auto focus and will pull in and out of focus until it gives up, switching to manual focus is not too much of a pain for me, but if you are counting on a good auto focus feature, ..  Read the complete review
