All lenses bearing the G Master brand from Sony are designed to high standards, and this one is Sony's new flagship. The Sony FE 600mm f/4 GM OSS Lens is characterized by its  super telephoto length, bright aperture, and lightweight design, making it an aspirational lens for sports, news, wildlife, and nature photographers using Sony E-mount mirrorless cameras
It is the world's lightest 600mm f/4, rated 10 grams lighter than the Canon EF 600/4 L IS III. It also is world's first aspherical 600mm f/4 lens. This feature, until now found only in smaller lenses used for portrait, now means you can get amazing bokehs even in super tele photo range.
A unique design element is that weight is taken off the front compared to other 600mm f/4 lenses. This decreases its rotational inertia making it easier to swing around while shooting sports.
