SIRUI 35mm f1.8 Anamorphic 1.33X Lens - L-Mount

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

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.

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).

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.

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

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

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.

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

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.

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).

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