Showing 1-2 of 2
20 November 2011
Conclusion: At its longest telephoto setting, the Sigma 70-300mm f/4-5.6 APO DG Macro lens has a 0.5x macro facility, similar to the Tamron 70-300mm Di LD Macro lens. The Sigma comes complete with a lens hood and soft pouch.
Pros: Close-focusing 0.5x macro ability in the 200-300mm zoom range, Impressive build quality at the price, Sharp at all but the longest telephoto setting
Cons: No optical stabilisation, Lacks Sigma's HSM autofocus, and the basic motor is quite noisy, Poor image contrast in dull lighting
