The world’s only super telephoto reflex lens with auto-focus capability. Its reflex design gives the amazing SAL-500F80 super telephoto lens a short barrel and compact, lightweight design, ideal for field work on wilderness and nature assignments. And its auto-focus capability makes it unique among reflex lenses of this class. Mounted to a Sony DSLR with APS-C sized sensor, this lens provides a field of view equivalent to a 750mm lens on a 35mm camera. This lens also takes advantage of Sony’s in-camera Super SteadyShot® image stabilization system to reduce blur by compensating for shaky hands.
