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.

Video shooters will also be pleased to find Power Focus functionality, which provides smooth, even focus while shooting movies. The magnesium alloy body of this lens is also dust- and moisture-resistant for protection while shooting in adverse conditions. A fixed tripod collar employs bearings to ensure smooth rotation, with a switch to engage or disengage click stops. When engaged, users can switch between horizontal and vertical orientations in 90° increments as required. The click stops can be disengaged when smooth, low-resistance operations are required.
