MTF Services releases RF-mount-converted versions of Sirui 1.33x anamorphic lenses


MTF Services have released new RF-mount-converted versions of the Sirui 1.33x anamorphic lenses. Users of the RED Komodo and Canon C70 can now enjoy using the Sirui 35mm f1.8 and 50mm f1.8 anamorphic lenses to shoot stunning 2.4:1 cinemascope images.

The bespoke converted lenses are based on the Micro 4/3 versions of the Sirui 50mm f1.8 and 35mm f1.8. Each lens retains its compact dimensions, allowing for easy handheld or gimbal operation. The conversion needs to be performed by MTF Services and requires precise mechanical modification of the lens to allow fitting of the new mount. The lenses are available pre-converted via authorised MTF Services dealers.

The Sirui anamorphic lenses are well known for creating an anamorphic look. The lenses have a 1.33x wider horizontal field-of-view, versus the vertical one. When the pictures are de-squeezed in post-production they turn from standard 16:9 or 17:9 ratio images into cinemascope letterbox ones. The result emulates the look often seen on big motion pictures, with horizontal blue streak highlights and bokeh with elongated defocused areas.

The RED Komodo sensor is fully covered by the image circle of both the Sirui 35mm and 50mm lenses converted by MTF Services. This means that full 6K resolution of the sensor can be used to create anamorphic images. Canon RF mount camera users can also benefit. The new Canon C70 is fully covered and can create 4K 2.4:1 anamorphic images with the MTF Services converted Sirui lenses. The Canon EOS R 4K video mode is also fully covered.

With the newer Canon EOS R5 the lens image circles do not fully cover the full-frame sensor, but can still be used if the user is prepared to accept the vignette effect and crop the image in post-production (this requires the user to shoot in full-frame mode and then crop the image in post production to the equivalent of around 1.35x crop).

The RF-mount-converted Sirui 50mm f1.8 anamorphic costs £499 (plus tax) for the base lens, plus £150 (plus tax) for the conversion. The 35mm f1.8 anamorphic costs £637 (plus tax) for the base lens, plus £150 (plus tax) for the conversion.

The size and weight of the MTF Services RF mount converted Sirui 1.33x anamorphic lenses makes them easy to handhold.
The RF-mount-converted lenses join the existing L-mount-converted Sirui anamorphic lenses announced earlier this week. MTF Services also convert the widely used Fujinon MK 18-55 T2.9 and MK 50-135mm T2.9 Cine zoom lenses to both RF and L-mount, broadening the lens options available to users.

Both lenses are available to order immediately from authorised MTF Services dealers or MTF Services.
