    The Next Step in the Evolution of Cinematic Photography and Filmmaking

    SIRUI anamorphic lenses offer unique optical performance, with optimized flare and bokeh in an affordable price tag

    SIRUI, a veteran Chinese camera accessories manufacturer, released its 50mm f/1.8 1.33x lens on Indiegogo on Dec. 10. SIRUI anamorphic lens produces image circle covering APS-C sensors and comes in versions with Sony E-mount, FUJIFILM X-mount, and Micro 4/3 mount. Weighing in at only 560g, this compact, sturdy, and durable lens is perfect for on-the-go filmmaking.

    SIRUI anamorphic lens is a must-have for filmmakers who want to create works with the widescreen aspect ratio and Hollywood-style lens flare. Compared to the traditional 50mm APS-C lens, it boosts the horizontal field of view by 33% to achieve a FOV equivalent to an APS-C 37.5mm lens. In a 16:9 setting, users can easily produce a cinematic 2.4:1 widescreen video.

    Built with a precision optical structure and multiple layers of nano-coating, SIRUI anamorphic camera lens will deliver a vivid, recognizable horizontal blue flare. Another characteristic of the SIRUI anamorphic lens is the out-of-focus elements. The lens has a large F1.8 aperture ring, which optimizes the depth of view to create an oval bokeh effect. Each lens has 10 aperture blades that create specular out-of-focus highlights and more pleasing bokeh.

    Adopted German-manufactured Schott optical glass lens elements, together with the robust aluminum body and copper core, the SIRUI anamorphic lens achieves focal length, zoom, and aperture with smooth, consistent precision to create ultra-wide rectangular aspect ratios.

    “Shooting anamorphic is notorious for being prohibitively expensive for indie filmmakers. We’ve made the lens smaller and lighter, and its affordable price allows everyone in the mass market to have a chance to produce film-level works, a meaningful way to promote photographic creations,” SIRUI Marketing Director Sonny Liu said.

  • This looks very very interesting. Can't wait to see a 40mm too.

  • They missed one important mirrorless mount - L-mount. Even this lens only for cropped sensor, I'd like shoot anamorphic in APSC mode of Lumix S1/S1H

  • They missed one important mirrorless mount - L-mount.

    It is most unpopular mount and it is not clear if it'll be around in 2 years.

  • Would love to see a better performing 2x lens from these guys, looks like they are on the right track

  • The lens, which enables 2.4:1 aspect ratio shooting, is available in mounts for Sony-E, Fujifilm X and Micro Four Thirds, and will retail for around $700 / £660. Designed to cover APS-C sized sensors the lens offers a field of view that equates to a 37.5mm lens, according to Sirui, as the optics increase the horizontal angle of coverage by 33%.

    The Sirui will start shipping out in April.

    Sirui 1.33x anamorphic lenses come to RED Komodo and Canon C70 with MTF Services RF-mount conversion

    Affordable 35mm f1.8 and 50mm f1.8 anamorphic lenses now available pre-converted to RF mount by UK lens specialists

    MTF Services have released new RF-mount-converted versions of the popular 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.

    Available from today, 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 MTF Services RF mount converted Sirui 50mm f1.8 1.33x anamorphic lens on the Canon EOS R.

    The Sirui anamorphic lenses are well known for creating a sought-after 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 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 website.

    MTF Services L-mount converted Sirui 1.33x anamorphic lenses unveiled

    Bespoke conversion of the popular Sirui 35mm and 50mm lenses by UK lens specialists are now available

    Exciting new creative possibilities open up for users of the popular Panasonic LUMIX S1H, S1 and S5 and other L-mount cameras, as MTF Services today announces a new lens duo with immediate availability. The new L-mount converted versions of the affordable Sirui 35mm f1.8 and 50mm f1.8 1.33x anamorphic lenses emulate the sought-after anamorphic look often seen on big motion pictures, with horizontal blue streak highlights and beautiful bokeh with elongated defocused areas.

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

    The LUMIX S1H, S1 and S5 feature both 4K S35 and 3.5K 4:3 anamorphic modes which can take full advantage of the Sirui lenses image circles. Both lenses have an image circle that completely covers Super35/APS-C. In 4K S35 mode the result once de-squeezed in post production is close to the 2.35:1. Using Panasonic's 3.5K 4:3 mode users can get the anamorphic look while still getting a 16:9 final image - ideal for some TV and commercial users.

    Using the L-mount converted Sirui lenses on the LUMIX S1H allows users to get a 16x9 aspect result and still maintain the anamorphic look. (Image credit: Jim Marks) The lenses can be used to cover a slightly larger area if the user is willing to accept some vignetting (this requires the user to shoot in Full-frame 5.9K mode and then crop the image in post production to the equivalent of around 1.35x crop)

    London-based DP Jim Marks has been using the lenses and is impressed. He said,"Previously our anamorphic lens options were either ruinously expensive or homemade. The MTF Services L-mount conversions of the Sirui 1.33x 35mm and 50mm are the missing pieces of the puzzle that finally allow Panasonic's anamorphic modes to be used in anger with lenses that are affordable, lightweight and easy to use. The lenses are fast, very sharp and enjoy smooth focus with a throw that aids the solo shooter. On my LUMIX S1H they create a simple handheld package, with the option to shoot regular 4K 16x9 for a 2.4:1 finished aspect, anamorphic 4K S35 mode for a 16x9 finish, or full-frame 5.9K with a slight crop in post for an even wider field of view. Set up like this I have a wonderfully portable combination that is truly fun to shoot with.

    L-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.

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