The Sirui 50mm f/1.8 is a dedicated 1.33x anamorphic prime for Sony E APS-C, and the f/1.8 aperture is what separates it from the wider f/2.8 anamorphic in the same lineup. It produces a 2.4:1 widescreen frame with a real squeeze, not a clip-on effect. The fast stop matters when you are shooting at night or trying to keep ISO down, and the all-metal barrel gives the lens a rigid feel without needing an adapter stack. With a 50mm APS-C focal length, this reads as a normal-to-short-telephoto lens, which suits a single shooter who wants an anamorphic character on a standard cinematic focal length.
Practical lights and reflections bring out blue anamorphic streaks, while the optics stay sharp enough that the anamorphic look comes from flares and oval bokeh instead of softness. The squeeze takes a moment to get used to: footage previews vertically stretched until you feed it to a monitor with 1.33x de-squeeze or add that step in post. That is standard for real anamorphic work, so it does not feel like a penalty. The f/1.8 maximum aperture also keeps handheld evening shots at a usable shutter speed while holding ISO in check.
This is for Sony E APS-C shooters who want a fast normal-FOV anamorphic at an entry-level price and are planning narrative close-ups or low-light scenes. The 50mm APS-C field of view is relatively tight for interior or gimbal work, and the 560g all-metal body is front-heavy on small mirrorless rigs. Neither is a defect if your shooting distance is under control and your rig has support.
Compared with the wider f/2.8 anamorphic in the same tier, this lens trades a roomy frame for one extra stop of light. For interviews or scripted scenes where the camera distance is set in advance, that trade favors the 50mm; for handheld walk-and-talk or small rooms, the wide sibling is the better fit. The build quality and image character are strong enough that this is the anamorphic prime to try first in the entry tier.
💡 Leave room around the 0.85m minimum focus when planning close shots, especially with a focus pull.
Pros
- True 1.33x anamorphic prime delivers 2.4:1 widescreen framing from a Sony E APS-C body.
- f/1.8 aperture keeps low-light shots usable and is the fastest stop in this tier.
- Sharp optics with controlled oval bokeh and blue flares create a clean cinematic image.
- All-metal build feels solid on a support rig and should handle regular field use.
Cons
- The 560g all-metal barrel can shift balance forward on small mirrorless bodies and gimbals.
- The 50mm APS-C field of view is tight for interior interviews and wide gimbal moves.
Sony E APS-C shooters who want anamorphic character and low-light speed get it here; the 24mm sibling covers wider spaces.
