Combining a super telephoto length, bright aperture, and lightweight design, the?FE 600mm f/4 GM OSS Lens?from?Sony?is designed for their E-mount cameras and is ideal for sports, news, wildlife, and nature photographers. The f/4 aperture and eleven-blade circular diaphragm provide great depth of field control for isolating subjects, as well as maximizing performance for low-light shooting situations. Three fluorite elements and one XA (extreme aspherical) element reduce chromatic aberration and color bleeding, while two ED (extra-low dispersion) elements and a Nano AR lens coating further increase performance and image quality by reducing flare, ghosting, and spherical aberations while shooting in harsh conditions. The front element is further protected by a fluorine coating that helps prevent dirt and fingerprints from sticking, while making it easier to wipe clean if they do become attached to the lens surface.

Weighing in at just 6.71 pounds, this lens is incredibly portable for glass of its size. The weight of the lens is also redistributed to the back to make it less front heavy, making tracking subjects and panning easier whether you?re shooting handheld or on a monopod. Complementing that is Sony?s XD (Extreme Dynamic) Linear Motor autofocus system, which is driven by two motors to quickly and quietly track subjects across the frame, even while shooting at high speeds. Furthermore, Optical SteadyShot can combine with in-body stabilization to provide 5-axis stabilization.
