The Canon RF-mount 35mm T2.9 Anamorphic 1.6x Lens from Sirui produces a wider look equivalent to a 22mm spherical full-frame field of view. Suitable for capturing architecture, landscapes, and confined spaces, this lens features rich detail, cinematic, oval bokeh, and artistic lens flairs. This lens produces horizontal blue streaks when pointed at a light source, giving your footage a dreamy or science fiction aesthetic. An image captured in 16:9 is de-squeezed to an anamorphic 2.8:1 aspect ratio, whereas shooting in 3:2 yields a 2.4:1 final image.

A key aspect of anamorphic lenses is oval bokeh, which can gently distort objects and lights in the distance, providing an abstract background for your actors. Its T2.9 aperture produces a shallow depth of field, blurring everything in front or behind the specifically chosen focal plane. This lens incorporates a 1/4"-20 mounting thread and has cine-style geared focus and aperture rings.

Full-Frame Coverage
Robust lens with advanced optics for full-frame cameras
Anamorphic Design
  • The 35mm anamorphic design provides the equivalent of a 22mm spherical field of view
  • Horizontal blue streak effects
  • 10 aperture blades produce an oval bokeh
Two Aspect Ratios
Produces a 2.4:1 aspect ratio when shooting in 3:2 format and a 2.8:1 aspect ratio in 16:9
Uniform Design
Matching color tones, identical gear positions, and a common T2.9-T16 aperture range make it easy to switch between lenses in the series

can this lens be used with the .71x speed booster on a c70?
Asked by: Luke
No, there isn't a speed booster that will adapt an RF lens, like the Sirui 35mm T2.9 1.6x Full-Frame Anamorphic Lens (Canon RF), on to the RF mount on the Canon EOS C70 Cinema Camera (RF Mount), B&H # CAEC70.

This lens will work in croped cameras as Sony FX30, it will perform normally being just the smaller FOV the only issue?
Asked by: Samuel
The Sirui 35mm T2.9 1.6x Full-Frame Anamorphic Lens (Sony E) is compatible with full frame sensors, as well as any other sensor, smaller than full frame. On a Sony FX30, this lens would act approximately as if used on a super 35mm sensor.

Is there a way to desqueeze the photo while shooting outdoor; a specific monitor with 1.6 desqueeze factor.
Asked by: Mohamed
When shooting outdoors with the Sirui 35mm T2.9 1.6x Full-Frame Anamorphic Lens (Sony E), displays that have a custom de-squeeze feature, like the PORTKEYS LH7P (B&H # POLH7PB), would allow for a 1.6 setting. This feature offers anamorphic image de-squeeze with all the standard ratios (i.e. 1.33x, 1.5x, and 2.0x) and the possibility to enter a custom aspect ratio from 0.25 to 4.0x.

Is this lens compatible with Sony Alpha A6700 ?

Is this lens compatible with Sony Alpha A6700 ?
Asked by: Aysun
The Sirui 35mm T2.9 1.6x Full-Frame Anamorphic Lens (Sony E) is a full frame lens, and the Sony A6700 is a APS-C sensor. We recommend Super 35 lenses for your camera model. Or you could work with a wider angle full frame lens (24mm) to cover the APS-C sensor of the A6700. We suggest working with an S35 sensor lens that will give you a 21:9 aspect (Wide) aspect ratio before the De-squeeze. Sirui 35mm T2.9 1.6x Full-Frame Anamorphic Lens (Sony E) BH #SIVENUSE35
