Sony FE 50-150mm f/2 GM Lens (Sony E) Review

The Sony FE 50-150mm f/2 GM is a flagship portrait and event zoom that breaks new ground with a constant f/2 aperture across the entire range. This is the fastest mid-telephoto zoom Sony has ever made, designed for professionals who need shallow depth of field, low-light performance, and flexible framing without changing lenses. The lens employs four XD Linear motors with floating focus for fast, quiet AF, and includes aperture de-click and lock switches to meet the needs of hybrid photo and video shooters.

Built with Sony's premium GM optical formula, the lens combines XA, aspherical, and Super ED elements with Nano AR Coating II to control flare and maintain sharpness. Internal zoom and focus keep the lens balanced on gimbals and rigs, while dust and moisture sealing ensures reliability in demanding conditions. At $3,998, it sits at the top of Sony's E-mount lineup and competes directly with exotic primes in terms of speed and cost. The weight and size will be significant, but that's the trade for constant f/2 performance in a zoom package.
