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.
