APO 200-500mm F2.8 EX DG
隨時美國攝影展PMA2007的開展，各鏡頭大廠都使出渾身解數發表旗下新開發的作品。Sigma亦不落人後，推出了史上最大口徑變焦鏡頭APO 200-500mm F2.8 EX DG，就是要攝影的新世界無限擴張。
APO 200-500mm F2.8 EX DG焦距為200-500mm，全區域光圈值可達F2.8。採用了4枚SLD特殊低分散鏡片，色收差等所有可能造成畫質低下的問題皆可幾近完美的補正。上市時間與價格都尚未訂出。
濾鏡從後方插入，利用獨自開發的回轉機構可支援圓偏光濾鏡。隨附專用的2倍TeleConverter「APO TELECONVETER 2x EX DG II」，裝上它，可進行400-1000mm變焦全區域光圈值F5.6的超望遠攝影。
The APO 200-500mm F2.8 EX DG is the world’s first Ultra-Telephoto Zoom Lens that offers a fast aperture of F2.8 at 500mm focal length. It covers the widely used 200 to 500mm focal length range, and maintains its fast F2.8 aperture over the entire zoom range. Four SLD (Special Low Dispersion) glass elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.
Shooting distance and focal length can be viewed on the lens' LCD panel, which is an additional convenience for the photographer.
A filter can be inserted towards the rear of the lens, and a circular polarizing filter can be used with its ingenious rotation mechanism.
A dedicated APO TELE CONVERTER 2x EX DG II is supplied as a standard accessory with the APO 200-500mm F2.8 EX DG.
Its exclusive design minimises image degradation usually associated with teleconverters. When this dedicated teleconverter is used with the APO 200-500mm F2.8 EX DG lens, it becomes a large aperture 400-1000mm F5.6 AF Ultra-Telephoto Zoom lens.
