Advantages: Decent quality on a budget but only for APS-C digital SLR's. Disadvantages: Really quite poor when used with full-frame digital SLR's.
of good quality. I don't know if it is simply a variation between samples but my own APO version appeared to have somewhat 'smoother' zooming than my friend's non APO one. As usual for Sigma, a decent lens hood (barrel type) and a soft case are included in the package. The lens sports a 58mm filter thread, so filters are relatively inexpensive to purchase.
Being of more 'ordinary' status in the Sigma hierarchy, this AF 70-300mmf/4-f/5.6 DG APO Macro, has none of the more elaborate 'bells and whistles' evident on the more expensive EX range. What does this mean? Well, you don't get Sigma's superb HSM (Hypersonic Motor) AF (auto-focusing) for near silent and very fast AF, resulting in a somewhat more unsophisticated, noisy (although not overly so) and slightly 'harsh' action.

This is a great lens and will suite most amateur photographers needs. The detail and sharpness even at full zoom is fantastic even when hand held.

I have taken this in my camera bag for an all day nature walk i had planed ...
This is a good quality lens that offers good value for money. It's a great lens for any canon enthusiast and incorporates plenty of features that I would highly recommend. This really is a wonderful piece of kit that should go well with many accessories because it really looks good. After using this product for a few months I have not so far come up against any reliability issues but only time will tell. I therefore would recommend the product. However, always think carefully as to whether you actually really need something before you buy it. We buy so many things nowadays that we don't really need.
