Our take on the SIRUI 40mm T1.8 1.33X S35 Frame Autofocus Anamorphic Lens

The Sirui 40mm T1.8 is an autofocus anamorphic lens for Super35 sensor cameras. It squeezes a 1.33x anamorphic image onto the sensor, giving a wider field of view and the oval bokeh and horizontal flares that anamorphic shooters want. Autofocus sets it apart from most anamorphic glass, which is manual only, so it suits solo shooters and gimbal work. The fast T1.8 aperture helps in low light and gives shallow depth of field. It is a niche lens: the anamorphic look comes with a heavier, larger body than a plain 40mm prime, and the 1.33x squeeze needs desqueezing in post or a monitor with an anamorphic mode.

Questions and answers

Does this lens autofocus on all cameras?
It has an autofocus motor, but performance depends on the camera body and its mount. Check that your camera supports autofocus with this lens.
What sensor does it cover?
It is built for Super35 sensors. Full-frame bodies would need a crop mode.
Do I need to desqueeze the footage?
Yes. The 1.33x squeeze must be desqueezed in post or viewed on a monitor with an anamorphic mode.
What is the aperture range?
It opens to T1.8, which is fast for an anamorphic lens and helps in low light.
Is it good for gimbal work?
Autofocus helps on a gimbal, but the lens is heavier than a standard prime, so check your gimbal's payload.
