Extend the range of your primary lens with the Sony SAL-20TC 2.0x teleconverter lens. Using the SAL-20TC, you can extend the photographic range of your primary lens by 2x, letting you cover more distance and capture more subjects without the burden of extra equipment. This extra range--when combined with the lens's compact size--makes it a hand accessory on long wilderness treks or while traveling on vacation. Even better, the lens offers a superb optical performance that preserves both the accuracy and the image quality of your primary lens. The SAL-20TC supports the G series 70-200mm f/2.8 G telephoto zoom, the G series 300mm f/2.8 G telephoto lenses, and the unique Sony 135mm f/2.8 STF (Smooth Transition Focus) lens. Note that photographers will have to compensate for their reduced light transmission by opening their apertures two steps with the 2x converter.
