Mount adapter manufacturer MTF Services is targeting videographers using L and RF mount cameras with a pair of low-cost anamorphic lenses. The company is converting the Sirui Micro Four Thirds 35mm and 50mm F1.
8 1. 33x anamorphic lenses to work with Leica L and Canon RF mount cameras.
These lenses have an imaging circle wider than the APS-C format, so they work with Super35 sensor areas and even with full-frame recording with a 1. 35x crop. With the Sirui 50mm F1. 8 costing just under $700/35mm F1. 8 costing less than $800/
To convert the lenses a slight modification is made to the rear of the lens barrel and the supplied mount is replaced with one of the company’s own stainless steel mounts. Once the conversion is done users can swop the mount themselves - so an adapted L mount lens can be used on both S and G series Lumix cameras. The conversion is only possible in the MFT versions of these lenses though, so when the adapted mount is removed only a MFT mount can replace it.
Users of Red’s 6K Komodo and Canon’s C70 will be able to use these lenses with the whole sensor of both models fully covered, just as anyone using Canon’s R series cameras and models from the L-mount Alliance will be able to shoot with them.
Panasonic S series cameras will be able to shoot 3. 5K 4:3 anamorphic footage as well as full 4K 16:9 video using the S35 mode. The 1. 33x anamorphic squeeze produced by these lenses makes footage recorded in the 4:3 Anamorphic Mode format desqueeze to 16:9, while shooting 4K 16:9 in the first place will deliver 2. 4:1 letterbox format.
As the covering circle is slightly larger than S35 the lenses can be used in full frame mode so long as you are prepared to apply a 1. 35x crop in post-production. DP Jim Marks says he uses the adjustable frame guides in his Lumix S1H to mark out where the crop will be needed when recording in the full-frame 5. 9K anamorphic mode, so he can compose the frame easily while shooting. He says what you end up with is about 4K-resolution but with a wider field a view than you’d get with a S35 or MFT sensor area.

The converted lenses cost an extra $200/rmation see the MTF Services website.
Press releases:
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 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 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.

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.
