The Canon RF-mount 50mm T2.9 Anamorphic 1.6x Lens, from Sirui, is designed for filling a theater screen with rich detail, cinematic bokeh, and artistic lens flairs. One of the signature features of this lens is that it produces horizontal blue streaks when pointed at a light source, giving your footage a dreamy or science fiction aesthetic. On full-frame cameras, this lens increases the horizontal angle of view by 60%, equivalent to a wider 31mm spherical lens, and it enables the camera to see well to the left and right of your subject. 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.

Sirui 50mm T2.9 Anamorphic FF Overview

By B&H Photo's

The Canon RF-mount 50mm T2.9 Anamorphic 1.6x Lens, from Sirui, is designed for filling a theater screen with rich detail, cinematic bokeh, and artistic lens flairs. One of the signature features of this lens is that it produces horizontal blue streaks when pointed at a light source, giving your footage a dreamy or science fiction aesthetic. On full-frame cameras, this lens increases the horizontal angle of view by 60%, equivalent to a wider 31mm spherical lens, and it enables the camera to see well to the left and right of your subject. 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. It features female 1/4"-20 threading for mounting versatility, and its focus and aperture rings are geared for use with a follow focus system.

Features
  • Robust lens with advanced optics for full frame cameras
  • Anamorphic design provides a 60% horizontal field of view increase over standard 50mm spherical lenses
  • Anamorphic 2.8:1 de-squeezed format from a 16:9 capture setting
  • German Schott optical glass
  • Super spectra coating
  • Horizontal blue streak effects
  • Ten aperture blades produce oval bokeh
  • 2.5' minimum focusing distance
  • 16 elements in 13 groups
  • M82 x 0.75 filter thread
  • Durable aluminum alloy lens housing

Is this lens adaptable to EF?
Asked by: BAIRN
No, unfortunately, the Sirui 50mm T2.9 Full Frame 1.6x Anamorphic Lens (Sony E), cannot be adapted or modified for use with an EF mount. Mirrorless lens must be closer to the sensor, and no adapter would be able to compensate.
