Mamiya/Sekor Auto SX 135mm F2.8 Cine Mod w/ Anamorphic Bokeh & Flare | Nikon Z!

🎬 Mamiya/Sekor Auto SX 135mm F2.8 Cine Mod for Nikon Z – Anamorphic Style Character Lens

This is a beautifully prepared Mamiya/Sekor Auto SX 135mm F2.8 Cine Mod lens, professionally adapted for Nikon Z mount and tuned for cinematography and professional video work. This particular lens has been modified to deliver a highly desirable anamorphic-style image character while remaining a practical spherical setup. It produces a neutral oval bokeh and attractive orange flares, giving your footage a widescreen cinema feel without the workflow complications of a true anamorphic lens. There is no need for de-squeezing in post-production – simply add 2.35:1 black bars for a rich cinematic presentation.

The lens is a strong creative option for filmmakers who want vintage rendering, flattering compression, and stylized highlights in a more compact and affordable package than dedicated anamorphic glass. At 135mm, it is especially well suited for portraits, music videos, detail shots, selective close-ups, atmospheric inserts, and controlled narrative work where separation and character matter. The longer focal length helps enhance the ovalized out-of-focus rendering and gives footage a refined, cinematic feel.

This copy has been fully serviced and cleaned, then adapted and adjusted for Nikon Z mount. It also covers full frame sensors, making it a versatile choice for modern Nikon Z cinema and hybrid cameras. The setup includes 2 follow focus gears for precise manual operation – one on the focus ring and one on the aperture ring, making the lens much more practical for rig use, follow focus systems, and controlled on-set work.

Optically, the glass is in pretty good condition. There is very minor wear visible on the glass, which is normal for a vintage lens of this age and does not affect the final image. Cosmetically, the lens presents very well as shown, and the cine-mod setup gives it a purposeful professional look ready for production use.
