Hot on the heels of its premium FE 35mm F1.4 GM, Sony has introduced another high-end prime lens. The FE 50mm F1.2 GM is clearly something of a statement optic which rebuts the notion that Sony’s relatively narrow-diameter E-mount might be limited in its ability to support large-aperture primes. The lens is also smaller, lighter and less expensive than its Canon and Nikon equivalents.

Indeed at 87mm in diameter, 108mm in length and 778g, the 50mm f/1.2 is only slightly larger than Sony’s existing Zeiss-badged FE 50mm F1.4 ZA, while weighing exactly the same. Optically it employs 14 elements in 10 groups, including 3 advanced aspherical (AA) elements that aim to deliver high cross-frame resolution even at maximum aperture, while suppressing chromatic aberration and producing attractive background blur free of unsightly ‘onion ring’ effects. Sony’s Nano AR Coating 2 is applied to combat flare and ghosting.

Operationally, the lens features an aperture ring marked in 1/3 stop increments that can be switched between clicked and clickless operation. It also sports dual AF stop buttons for both portrait and landscape format shooting, along with an AF/MF switch. Four XD linear motors drive the internal focusing mechanism, while Sony’s Linear Response MF should deliver a tactile and intuitive manual focusing experience. As expected, the barrel benefits from dust- and splash-resistant construction. A robust bowl-shaped lens hood is supplied, and the lens accepts 72mm filters.

Due to hit the shops in April, the lens will cost £2,100. You can read our full, in-depth review of the Sony FE 50mm F1.2 GM here
