Sirui Astra 50mm
With a 44mm image circle covering full-frame sensors, a constant T1.8 aperture, and 1.33x anamorphic squeeze for native 2.35:1 output, this autofocus, weather-sealed lens delivers cinematic character with reliable stabilization. Selectable blue or neutral flares and an AF/MF switch supporting LiDAR follow-focus provide direct, precise look control rarely seen in anamorphic primes. It’s best for independent filmmakers and portrait shooters needing anamorphic rendering and low-light flexibility in close-up scenarios on Sony E-mount bodies.
