Ricoh Rikenon 50mm F2 Cine Mod Prime w/ Blue Anamorphic Bokeh & Flare | Canon EF

🎬 Ricoh Rikenon 50mm F2 Cine Mod – Blue Anamorphic Bokeh & Flare | Canon EF

TerPhoto presents a professionally serviced and cine-modified Ricoh Rikenon 50mm F2, transformed from a classic Japanese manual-focus photographic prime into a distinctive filmmaking lens for Canon EF cameras and cinema rigs.

This modification is designed for filmmakers who want an anamorphic-inspired aesthetic from a spherical lens without an anamorphic adapter or post-production de-squeeze workflow. The optical modification creates distinctive blue oval bokeh and beautiful blue flare characteristics, giving highlights and out-of-focus areas a more stylized cinematic personality. Because the lens remains spherical, footage does not require de-squeezing. For an anamorphic-style presentation, simply crop or add black bars to a 2.35:1 aspect ratio during post-production.

The aperture mechanism has been de-clicked, allowing smooth iris changes during video recording instead of the stepped movement of the original photographic aperture ring. A follow-focus gear is installed on the focusing ring, making the lens practical with standard cinema follow-focus systems and enabling controlled manual focus pulls.

This individual lens has been fully cleaned, adjusted and re-lubricated. It has also been professionally adapted and adjusted for Canon EF mount. The lens provides full-frame sensor coverage, making it suitable for full-frame Canon EF cameras and compatible cinema-camera setups as well as smaller sensor formats where the appropriate EF mount is available.

The glass is in good vintage condition. There is very minor age-related wear on the glass, typical for vintage optics of this period, which does not affect the final image in normal shooting conditions. The exterior has normal minor signs of previous use consistent with its age. Please examine the supplied photographs carefully, as they show the actual lens offered for sale.

The original Ricoh Rikenon 50mm F2 belongs to Ricoh’s classic manual-focus 35mm SLR lens family. Ricoh moved into the K-mount SLR system in the late 1970s, and the 50mm F2 became one of the company’s standard normal primes. The plain RIKENON 50mm F2 generation represented in this listing followed the earlier XR-branded versions and dates to around 1982. Period/model references describe this generation as using a traditional 6-element, 5-group optical construction.

Rather than trying to make this vintage optic behave like a clinically modern lens, the TerPhoto modification builds on its vintage rendering and gives it a more pronounced cinema-oriented personality.

🎥 Why Choose This Lens?

The Rikenon 50mm F2 Cine Mod combines genuine vintage Japanese optics with practical cinema modifications and a deliberately stylized anamorphic-inspired look. The 50mm focal length is highly versatile for narrative filmmaking, portraits, interviews, music videos and commercial productions, while F2 provides useful low-light capability and shallow depth of field. Blue oval bokeh and blue flare characteristics add visual personality without requiring a true anamorphic lens or de-squeeze workflow. The de-clicked aperture, geared manual focus, Canon EF adaptation, full-frame coverage and 80mm OD cine hood make this vintage prime far easier to integrate into a modern filmmaking setup.
