SIRUI just announced a new lens on Indiegogo, the 40mm T1.8 1.33x S35 AF anamorphic lens. This fast, compact lens combines a cinematic, anamorphic look with fast autofocus. The full campaign is set to go live on November 25th. Let’s take a closer look!

SIRUI is known for affordable accessories and recently launched their Aurora series consisting of fast, autofocus lenses for full-frame, mirrorless cameras. My colleague Graham also reviewed their 18-36° Projector Zoom Lens for COB lights in case you missed it.

SIRUI 40mm T1.8 1.33x S35 AF anamorphic prime lens – features

The SIRUI 40mm T1.8 1.33x S35 AF is unique in that anamorphic lenses are usually manual focus. This new lens features fast and precise autofocus with an advanced STM motor. Meanwhile, the lens also includes eye focus capabilities, making subject tracking easier while filming or shooting photos. The autofocus feature can be turned off for manual use. Minimum focusing distance is 0.6 m (1.97 ft.), along with a diameter of 77mm. The focal length equivalent is 42mm.

The BLAZAR APEX 35mm and 50mm anamorphic lenses, recently announced at IBC 2024, also feature autofocus. You can read up on my colleague Johnnie’s review of both BLAZAR APEX lenses here.

Combining the 1.33x squeeze and filming in 16:9 will result in a very cinematic, widescreen 2.35:1 aspect ratio. There is no need to crop the image to get the widescreen look. Additionally, SIRUI states that colors remain accurate and vibrant. There are also two flares available per the light source used, neutral or blue.

The T1.8 aperture is fast and works well in low-light situations, so a high ISO is unnecessary. Images can retain soft bokeh while subjects remain sharp, even in dim lighting. Minimum aperture is T22, and it features a step-less aperture design.

SIRUI kept the lens design compact with a weight of just 614g (1.35 lbs.), making it easy to carry and perfect for run-and-gun shooting. The autofocus is also very helpful with filming on the go. E, MFT, Z and X mounts are supported.

In addition, my colleague Johnnie Behiri is working on a review of the SIRUI 40mm T1.8 1.33x S35 AF anamorphic prime lens.

SIRUI has recently released several lenses, including the Aurora series, starting with a fast full-frame 85mm F1.4 AF prime. The new lens will work with full-frame mirrorless cameras and will be joined by five more lenses in the series.

The SIRUI 40mm T1.8 1.33x S35 AF anamorphic lens will launch on Indiegogo on November 25, 2024. Check out the campaign here for more information, pricing, and specials.
