Sigma’s 70-300mm has an impressive list of features but it also calls forth the warning that if something sounds too good to be true, then maybe that’s exactly what it is. Its 70-300mm focal-length range may be more than many users will really need in an everyday tele-zoom but there is nothing wrong with having a little bit of extra power – provided, that is, nothing more essential has to be sacrificed along the way.
