Product Information

Full details

This SIRUI 35mm f1.8 Anamorphic 1.33X Lens is designed for filmmakers seeking an authentic widescreen cinematic look. Its primary benefit is the 1.33x anamorphic squeeze, which delivers classic horizontal lens flares and an expanded field of view for a true 2.4:1 aspect ratio. A potential caveat is its specific compatibility with L-Mount cameras and its Super-35 format optimization, which requires a crop on full-frame sensors. Key features include a fast f1.8 aperture for low-light performance, exceptional optical quality with Schott glass, and a durable aerospace alloy construction.

FAQs

What aspect ratio does this lens produce?

This lens produces a native 2.4:1 aspect ratio when de-squeezed in post-production, due to its 1.33x anamorphic squeeze.

Is this lens suitable for full-frame cameras?

Yes, it is designed for Super-35 format but can be used on full-frame cameras by utilizing the camera's crop mode. This ensures optimal performance and image quality within the designated sensor area.

How do I achieve the anamorphic look (flares, oval bokeh)?

The anamorphic look, including horizontal flares and oval bokeh, is inherent to the lens design. Flares appear when light sources are present in the frame, and bokeh shape is primarily determined by the aperture setting (wider apertures create more oval bokeh).

Can I use this lens with autofocus?

This is a manual focus lens. Autofocus is not supported. The dual-gear system is designed for precise manual control and integration with follow-focus systems.

What is the minimum focus distance?

The minimum focus distance is 0.85 meters (2.79 feet), allowing for relatively close-up shots while maintaining the anamorphic perspective.

Does the lens have weather sealing?

The product information does not specify weather sealing. It is recommended to protect the lens from harsh weather conditions.

What is the benefit of the f1.8 aperture?

The fast f1.8 aperture allows for shooting in low-light conditions without excessively high ISO, and it enables the creation of a shallow depth of field for subject isolation and aesthetic bokeh.

Troubleshooting

Lens not mounting securely

Ensure there are no obstructions or debris on the camera mount or lens mount. Verify you are using an L-Mount camera body.

Image appears stretched or distorted horizontally

This is the intended anamorphic effect. To correct it for viewing or editing, you will need to de-squeeze the footage in post-production using video editing software that supports anamorphic footage or by applying a 1.33x horizontal stretch.

Flares or bokeh not appearing as expected

Anamorphic artifacts are heavily influenced by the light source and aperture setting. Ensure you are shooting with distinct light sources for flares and adjust the aperture to change bokeh shape (oval at wide, starburst at narrow).

Focus ring is stiff or jerky

Ensure the lens is properly mounted. If the issue persists, it may require professional servicing. Avoid forcing the ring.

Pros and Cons

Pros

  • Delivers authentic widescreen 2.4:1 aspect ratio footage natively.
  • Produces classic horizontal anamorphic lens flares.
  • Excellent low-light performance due to the f1.8 maximum aperture.
  • High-quality optics provide sharp images with minimal distortion and chromatic aberration.
  • Robust build quality ensures durability for professional use.
  • Smooth manual focus and aperture control with dual gears for follow-focus systems.

Cons

  • Requires a crop mode on full-frame cameras to maintain Super-35 optimization.
  • Anamorphic distortion (vertical stretching) is inherent and must be accounted for.
  • Specific L-Mount compatibility limits use with other camera systems without an adapter.
  • Manual focus operation demands precision, especially for video.
  • The distinct anamorphic look may not be suitable for all types of projects.

Setup, Compatibility & Care

Setup: Mount the SIRUI 35mm f1.8 Anamorphic lens directly onto your L-Mount camera body. Ensure the mount clicks securely into place. For video recording, it is recommended to enable your camera's Super-35 crop mode if using a full-frame camera to take full advantage of the lens's optical design. Engage the manual focus and aperture rings to your desired settings. For use with professional accessories, attach your follow-focus system to the integrated gears.

Compatibility: This lens is specifically designed for cameras featuring the L-Mount. It is optimized for Super-35 sensor formats, but can be used on full-frame cameras with a crop factor applied. Always check your camera's manual for specific anamorphic shooting modes or recommendations.

Care: To maintain optimal performance, keep the lens elements clean. Use a soft lens brush or a blower to remove dust. For fingerprints or smudges, use a microfiber lens cloth with a specialized lens cleaning solution. Avoid touching the lens elements directly. Store the lens in its protective case when not in use, away from extreme temperatures and humidity. Regularly check the mount for any debris.
