The Sigma 70-300mm F4-5.6 DG OS lens is a consumer-oriented lens and is available for Canon, Nikon, Sony, Pentax and Sigma DSLRs. This lens is one that is relatively compact for its abilities. It feels very light in your hands and should be very enjoyable for amateurs, enthusiasts, etc. Granted, the lens is not an EX (Sigma’s top of the line) and it surely shows it. I received some brief hands-on time with the lens and was able to judge the Canon version’s abilities vs. something like my much older Canon 80-200mm F2.8 L.
