Sony Alpha SEL50150GM 50-150mm F2 GM FE FF Lens

Innovative optical design and manufacturing achieve unprecedented performance. Two precision XA (extreme aspherical) elements in a state-of-the-art optical design plus meticulously controlled aberration deliver breathtaking resolution at all apertures, including F2. Two Super ED (Extra-low Dispersion) and three ED glass elements minimise chromatic aberration, while Nano AR Coating II suppresses flare and ghosting.

This large aperture telephoto zoom offers easy handling with a weight of just 1340 g (47.3 oz., without tripod base) and a length of 200 mm (7-7/8 in). Despite its large aperture it can be handheld with minimum stress. Internal zoom contributes to excellent balance that optimises handling for indoor sports or similar subjects. The 50-150 mm range allows uninterrupted shooting without the need for lens changes in many situations.

Four precision XD (extreme dynamic) linear motors drive the focus group for fast, accurate, quiet focusing that maximises the AF performance potential of modern camera bodies. Tracking easily keeps up with the 120 fps⁵ maximum burst speed of the α9 III and is consistently reliable even while zooming. This is a perfect lens for professionals whose jobs depend on getting the shot.

Focus breathing is effectively reduced for smooth movie imagery, and Linear Response MF allows precise manual focusing for maximum sharpness and resolution. Rack focus and zoom effects can be used with F2 depth of field to create natural transitions that guide the viewer’s eye. Critical focus for high frame rate 4K 120p/FHD 240p ⁶ recording is easy, and the entire system operates with minimal noise and vibration.

Operability is enhanced by an aperture ring with click ON/OFF and lock switches, three assignable focus hold buttons, and a DMF switch that enables temporary switchover to manual focus while using AF. And although it is a relatively large lens, ample clearance is provided for the camera grip. The removable tripod foot has 1/4” and 3/8” screw holes, and a dust/moisture resistant design ensures maximum reliability.⁷
