Sirui Astra Series 1.33× Full-Frame AF Anamorphic Cine Lens Kit (Sony E-mount, Neutral Flare)

The Sirui Astra Series 50mm, 75mm & 100mm – E Mount, Neutral 3Kit  three-lens anamorphic cine set:

The Sirui Astra AF 1.33× Full-Frame Anamorphic Lens Kit is a premium cine lens set designed to give filmmakers a complete, cinematic toolkit. The kit includes three fully matched, autofocus anamorphic primes — 50 mm, 75 mm, and 100 mm — all with a constant T1.8 aperture and 1.33× squeeze. This combination lets you shoot with a consistent look across wide, standard, and telephoto focal lengths, all while preserving the classic anamorphic 2.35:1 aspect ratio (on 16:9 sensors).

Reliable build quality.

• This kit is particularly powerful for narrative productions, short films, commercials, or any project where cohesive visual style matters. The lenses are built with durable aluminium alloy bodies and feature dust, dirt, and raindrop protection. Each lens uses a silent STM autofocus motor and supports full manual override with an AF/MF switch, AF lock (FN), iris lock, and selectable clicked or de-clicked aperture. The kit comes in a robust safety case, making it ideal for transport and professional environments.
