The Sony 70-200mm F2.8 G is one of the original group of lenses announced at the launch of the company's Alpha system in June 2006. However its history goes back a bit further; it's essentially a re-badge of the Minolta AF 70-200mm F2.8 APO G D SSM, which first appeared early in 2003. At the time Minolta was only making film SLRs (its first truly practical digital design, the Maxxum/Dynax 7D, appearing after the merger with Konica in September 2004), so the lens is designed to cover the 35mm full-frame format, although naturally it also works on APS-C digital SLRs. It's therefore a natural companion to the Alpha 850 and 900 DSLRs, providing a real alternative to Canon and Nikon systems towards the top end of the market.
Like all fast telezooms, the optical formula is complex, with 19 elements in 16 groups and 4 Extra-Low Dispersion (ED) glass elements for the correction of chromatic aberration. The lens features a built-in ultrasonic-type 'Super Sonic Wave Motor' (SSM) for autofocus, promising fast and silent focusing. The Direct Manual Focus feature allows the user to tweak focus position manually at any time, and has two modes; 'Standard' prevents accidental movements of the focus ring from interfering with continuous AF operation, while 'Full Time' is essentially self-explanatory. The lens also features three AF-stop buttons arranged around the barrel, allowing the user to lock focus easily; on Sony's latest high-end DSLRs these can be assigned to other functions, perhaps most usefully depth of field preview.
The 70-200mm F2.8G faces strong competition, though, from similar lenses such as the Sigma 70-200mm F2.8 EX DG Macro HSM II and Tamron SP AF 70-200mm F2.8 Di LD (IF) Macro. And the value proposition between these lenses becomes somewhat complicated on the Alpha system; because while Canon and Nikon's expensive fast telezooms add image stabilization and weathersealing, this isn't the case with the Sony (because all lenses are stabilized via the in-body Super SteadyShot system). The Sony lens therefore offers relatively little on paper to justify costing more than twice as much, but of course specification comparisons never quite tell the whole story. So let's see what you actually get for your money.
