Experience the cinematic power of the Sirui Astra 75mm T1.8 Anamorphic lens on the Lumix S9 and S5II. This professional cine lens brings a native 2.35:1 aspect ratio to your footage, offering a high-end film look with reliable autofocus performance.
In this review, I test the 75mm Astra in real-world scenarios, covering its build quality, blue and neutral flare options, and how it handles on the latest Lumix bodies. Whether you’re shooting documentaries or commercial projects, see why this anamorphic glass is a strong addition to any L-mount kit.
Key features explored:
Reliable Autofocus: Testing human detection and focus transitions on the S5II and S9.
Professional Build: Features de-clicked aperture, iris locks, and 82mm filter threads.
Comparison: How the 75mm compares to the 50mm Astra for field of view and versatility.
L-Mount Stabilization: Best settings for using anamorphic lenses with Lumix IBIS.
