摘要

This lens is a stable-mate for Sony's entry-level 75-300mm zoom (reviewed on the facing page). It offers a shade more zoom range (70-300mm) and benefits from both an SSM AF drive and ED glass. It is also almost exactly four times the price of its lesser sibling. Given that both lenses share the same maximum aperture (f/4.5-5.6) it is surprising how much bigger and heavier the more costly lens is. The barrel is uniformly cylindrical along its length with a broad zoom collar at the front and a narrower focusing collar mid barrel, behind which sits a focused-distance window.
