    Cons: Compared to any othe \"kit\" lens (Nikon) it was so much better than anything else.

    Pros: Sometime (mostly in cold wether) the aperture not work

    Summary: See \"cons\". So it\'s unique for the price

    Cons: A bit soft on the edge at wide angle. So It is needed to close the diaph at at least 5.6 or raise the focal a little bit.

    Pros: Useful range. Lightweight. Aberrations are not bothersome. Very sharp on the centre. Ideal for travelling.

    Summary: Very good value / price ratio if you want to avoid weak zooms sold with high value bodies.

    Cons: very weak in the corners at wide end even stopped down

    Pros: color rendition, sharp images at center of frame, accurate AF

    Summary: Improvement over the prior Sigma 17-70 offering but still lacking
