Sirui 75mm F1.8 1.33x Anamorphic Lens - Sony E

An anamorphic lens optically squeezes a wider field of view horizontally onto a standard sensor. In post-production, this is de-squeezed to create a widescreen aspect ratio (like 2.4:1) with unique visual characteristics such as oval bokeh and horizontal flares, giving footage a distinct cinematic look.

Yes, all 1.33x anamorphic lenses, including the Sirui SR75, require de-squeezing in video editing software to display the image at its intended widescreen aspect ratio.

The closest focusing distance is 1.2 meters (approximately 3.9 feet).

The Sirui SR75 lens is designed to cover APS-C sensors. While it might physically mount on some full-frame cameras, it will likely produce significant vignetting and a circular image that doesn't fully utilize the sensor.

The maximum aperture is f/1.8.

The lens does not come with a traditional screw-on lens hood, but its design aims to minimize internal reflections. Users may opt for third-party solutions if necessary.

This anamorphic lens produces oval-shaped bokeh, which is a characteristic and desirable trait of anamorphic lenses.

This is normal during shooting. You need to de-squeeze the footage in your video editing software during post-production to achieve the correct aspect ratio.

Ensure the lens is properly mounted and locked into the camera's E-mount. Check your camera's settings to ensure it allows shooting without a lens if applicable.

Practice manual focusing, especially with subjects at different distances. Use your camera's focus peaking or magnification features to aid in achieving critical focus.

While some flares are characteristic of anamorphic lenses, unwanted internal reflections can occur. Ensure your lens hood (if applicable) is clean and properly attached. Shooting away from direct light sources can also help manage flares.

Vignetting is common when shooting at the widest aperture (f/1.8) or with certain camera bodies. Stopping down the aperture to f/2.8 or f/4 should reduce or eliminate vignetting. Ensure the lens is fully compatible with your specific camera body.
