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.
