SIRUI 35mm F1.8 1.33X APS-C Cinema Lens (M4/3 Mount)
The lens uses a 1.33x squeeze to widen the horizontal field of view, effectively simulating a longer focal length for cinematic widescreen results. It achieves a broader look without post-cropping and supports a consistent anamorphic effect as aperture changes. Best for shooters who want a compact setup with pronounced horizontal emphasis and recognizable starbursts at stop-downs. The 26.3mm to 33% wider field of view makes it suitable for dynamic scenes where space is limited.
Who it’s best for: indie filmmakers and videographers seeking a lightweight, affordable option for an APS-C sensor with an M4/3 mount. Why selected: strong balance of anamorphic look, size, and the 1.33x squeeze factor.
Caution: The M4/3 mount compatibility requires adapter considerations depending on your camera body and lens configuration.
SIRUI 50mm F1.8 1.33X APS-C Anamorphic Lens for E Mount
Designed for E-mount cameras, this lens delivers a 1.33x squeeze that widens the horizontal field of view, approximating a broader 37.5 mm perspective. It emphasizes cinema-ready looks with a compact, lightweight build. The source elements are described as premium, with emphasis on a blue flare aesthetic that complements the anamorphic signature. The lens is best for people shooting on Sony bodies who want a versatile normal-telephoto option with a cinematic feel.
Who it’s best for: Sony users seeking a mid-telephoto anamorphic option for stylish widescreen looks. Why selected: balance of focal length, squeeze, and overall cinematic character.
Caution: The blue flare and optical character are distinctive; those seeking minimal aberrations may find it more pronounced in certain lighting.
SIRUI 24mm Anamorphic F2.8 1.33X APS-C
With a shorter focal length, this lens broadens the horizon more aggressively, enabling expansive 2.4:1 framing in tight spaces. It also reduces the minimum focusing distance to 0.6 meters, aiding close-up storytelling when space is constrained. The 1.33x squeeze yields familiar anamorphic cues, including blue light streaks and oval bokeh beyond the standard 16:9 frame. This makes it a strong choice for landscape-heavy shoots or interiors where the wider foreground matters.
Who it’s best for: travel-style or documentary shooters needing a wide look without large gear. Why selected: wide field of view with practical close focusing for tighter interiors.
Caution: The 24mm’s wider view can exaggerate perspective; plan framing to maintain subject separation in cluttered scenes.
SIRUI 75mm F1.8 1.33X APS-C (Z Mount)
With a 75 mm focal length and a 1.33x squeeze, this lens produces a distinctly telephoto anamorphic look, expanding horizontal framing while maintaining subject isolation. It uses a robust Z-mount and a lightweight aviation aluminum alloy body with Germany-made Schott glass. The closest focusing distance is 1.2 meters, making it suitable for portraits and distant subjects where a cinematic compression is desired. Best for: filmmakers who want longer reach without sacrificing anamorphic authenticity.
Caution: Telephoto anamorphic optics can exaggerate perspective; balance subject distance to avoid excessive compression in tight spaces.
SIRUI 75mm F1.8 1.33X APS-C (X Mount)
This X-mount option mirrors the Z-mount variant with a 75 mm focal length and 1.33x squeeze, designed for cameras that use the X-mount system. It shares the same cinematic benefits—2.4:1 framing, oval bokeh, and distinct light streaks—while offering mounting compatibility with X-series bodies. Best for: creators using Sony’s or other X-mount platforms seeking a premium telephoto anamorphic option. Why selected: coherent optical design across mounts and strong cinematic potential.
Caution: Ensure your camera’s mount compatibility and adapter requirements align with the lens lineup to avoid fit issues.
SIRUI 75mm F1.8 1.33X APS-C (EF-M Mount)
This EF-M mount option brings the anamorphic 75 mm look to mirrorless cameras using the EF-M system, preserving the same 1.33x squeeze and cinematic 2.4:1 framing. It is a fitting choice for shooters with EF-M bodies seeking elevated subject compression and a crisp, cinematic edge. Best for: EOS M users who want a dedicated anamorphic look without changing camera platforms. Why selected: mount-specific adaptability without compromising the core anamorphic character.
Caution: EF-M cameras have smaller ecosystems; check lens compatibility and availability of future control features on your body.
Buying Guide: Key Considerations When Choosing a C Mount Anamorphic Lens
Why choose an anamorphic lens? The signature widescreen look, light streaks, and oval bokeh differentiate cinematic footage from typical 16:9 imagery. When selecting among the options, consider compatibility, field of view, and the desired storytelling impact.
- Focal Length and Field of View: Wider focal lengths (24 mm, 35 mm) provide broader horizontal framing on APS-C bodies, while longer focal lengths (75 mm) offer more subject compression and a telephoto anamorphic effect.
- Squeeze Factor: All listed options use a 1.33x squeeze. This preserves the classic 2.4:1 cinema look without major post-cropping, but always verify how the squeeze translates on your sensor.
- Mount Compatibility: Ensure your camera supports the chosen mount (E, Z, X, EF-M, M4/3). Some lenses require adapters, which can affect size, weight, and infinity focus.
- Light and Build Quality: Premium materials, such as aviation-grade aluminum and high-quality glass (German Schott glass), improve durability and optical performance in varied lighting.
- Aesthetic Trade-offs: Anamorphic optics introduce characteristic flare and light streaks that are more pronounced at certain apertures. Decide if this aligns with your creative goals or if you prefer subtler effects.
- Minimum Focusing Distance: Shorter minimum distances (e.g., 0.6 m for the 24 mm) enable closer subject work in tight spaces, which can influence shot composition.
