Overview

The Sony FE 50-150mm F2 GM is a unique constant-aperture zoom offering prime-like resolution and exceptional sharpness wide open, even at f/2. It excels for portraits, events, and indoor sports, but its 50-150mm range is considered limiting by some. Build quality is premium with internal zoom, though it is large and heavy. Weaknesses include moderate color blur, lateral CA, and strong flare at narrow apertures. It suits professionals who need a fast telephoto zoom and can justify the high price, but many may prefer primes or the Tamron 35-150mm.
