SIRUI Astra 50mm 1.33X Autofocus Anamorphic, E/FX/A7R Series
Best for full‑frame cinema workflows that demand an authentic anamorphic look with reliable autofocus. The Astra 50mm covers full‑frame sensors with a 44mm image circle and provides a constant 1.33x squeeze for a native 2.35:1 result. Dual flare options let you tailor the flare to blue or neutral styles, giving you versatility across genres such as indie features and high‑end commercials.
Who it’s for: independent filmmakers and professional videographers who want a single, high‑quality anamorphic lens for full‑frame cameras. Why selected: it combines full‑frame coverage, consistent squeeze, and selectable flares in one ready‑to‑shoot package.
Caution: The weight and size can be more demanding on lighter setups; ensure your rig supports the lens balance and mount compatibility for extended shoots.
SIRUI 20mm T1.8 1.33X Anamorphic Autofocus (S35)
Best for wide cinematic storytelling on APS‑C or Super 35 sensors with autofocus support. The 20mm focal length provides expansive framing while the 1.33x anamorphic squeeze yields a dramatic 2.35:1 output in 16:9, preserving a broad field of view without cropping. Eye tracking and an AF/MF switch give on‑the‑shoot creative control.
Who it’s for: shooters needing a wide anamorphic option with reliable autofocus for travel, interview setups, or interior scenes. Why selected: its balance of wide perspective, autofocus, and S35 coverage fits many modern workflows.
Caution: The 37mm image circle supports S35 well but may not cover full‑frame sensors—avoid using on full‑frame bodies unless your project intentionally crops to S35.
SIRUI 40mm T1.8 1.33X Anamorphic Autofocus (S35)
Best for mid‑length storytelling with a cinematic look. The 40mm focal length offers natural perspective for portraits and scenes with moderate depth. Autofocus with an advanced STM motor supports eye tracking and subject tracking, while dual flare options let you tailor the frame’s aesthetic.
Who it’s for: cinematographers and creators seeking a versatile standard focal length with strong autofocus for 2.35:1 output. Why selected: provides a strong middle ground between wide and telephoto, plus reliable autofocus in a compact package.
Caution: Flare behavior can vary with lighting; plan lensing around strong backlight to manage flare intensity.
Samyang Cine Auto Focus 24mm T1.9 (Sony E)
Best for generalist, fast‑moving shoots that still crave a wide field and cinematic depth. The 24mm focal length delivers broad scenes with a 2.35:1 potential when used with anamorphic workflows. It features a Focus Hold button, a customizable switch, and a tally lamp indicator for monitoring recording status on set.
Who it’s for: video crews and solo operators needing a compact, versatile wide lens with focus controls and a clear recording status pad. Why selected: combines strong autofocus performance with practical Cine AF controls and 8K readiness signals across production pipelines.
Caution: Some users may find the 24mm field of view tight in very cramped interiors; verify space in advance for smooth movement and framing.
SIRUI Astra 75mm 1.33X Autofocus Anamorphic
Best for tighter compositions and portraits with a cinematic telephoto look. The 75mm focal length provides compression and subject separation while maintaining the 1.33x anamorphic squeeze for a 2.35:1 final image. It uses the Astra family’s autofocus system and dual flare options for distinctive light streaks.
Who it’s for: filmmakers focusing on character work or closeups in larger scenes, or projects needing a more intimate camera angle. Why selected: extends the autofocus anamorphic family to a longer focal length, expanding creative options.
Caution: Telephoto anamorphic lenses can exaggerate camera shake; stable support and smooth rigs are advised for handheld or moving shots.
Buying Guide: Key Considerations For Cine Lenses With Autofocus
- Sensor Coverage: Decide between Full Frame and Super 35/S35 coverage. Lenses labeled “Full Frame” typically cover higher sensor sizes but may be heavier.
- Autofocus Performance: Look for lenses with an STM or similar focus motor, eye tracking, and AF/MF controls for smooth transitions during takes.
- Anamorphic Squeeze: A 1.33x squeeze is common; it preserves 2.35:1 output without cropping, but verify your camera’s crop factor and de-squeeze method.
- Flare Options: Dual flare (blue and neutral) gives creative flexibility; consider your lighting setup and preferred look for shoots.
- Weight and Balance: Autofocus anamorphic lenses can be heavier. Ensure your rig supports balanced handling for handheld or gimbal work.
- Image Circle and Coverage: Confirm the image circle matches your camera’s sensor size to avoid vignetting at the frame edges.
- Tracking and Subject Motion: For dynamic scenes, prioritize lenses with stable AF performance and smooth focus transitions.
- Compatibility: Check mount options (E, L, etc.) and your camera’s autofocus capabilities to maximize reliability on set.
FAQ
- What is the benefit of a 1.33x anamorphic squeeze?
It yields a cinematic 2.35:1 aspect ratio without cropping, preserving field of view while giving characteristic anamorphic flares. - Are autofocus anamorphic lenses suitable for run‑and‑gun shooting?
Yes, if they include reliable AF, compact design for your body rig, and quick, consistent focus pulls in varied lighting. - Can these lenses be used on full‑frame and APS‑C cameras?
Some are designed for full‑frame sensors; others are optimized for Super 35. Verify the image circle and sensor coverage for your camera. - Do anamorphic lenses require de‑rolling or post processing?
Yes, de‑squeezing is typically done in post or via in‑camera desqueeze options to achieve the final widescreen look. - Is autofocus slower with anamorphic optics?
Autofocus speeds can vary; some lenses prioritize smooth, cinematic focus rather than rapid AF bursts, especially in low light. - Which focal length should I start with for film projects?
Start with versatile options like 40mm or 50mm for general storytelling, then add wider or longer focal lengths as needed.
