Megadap M2RF unveiled, enables Leica M lenses to autofocus on Canon RF

Megadap unveiled the M2RF, a motorized autofocus adapter that enables Leica M‑mount lenses to autofocus on Canon RF‑mount cameras. Megadap billed the product as “the world’s first Leica M to Canon RF autofocus adapter,” and the adapter was shown publicly during CP+ with the company’s announcement published February 26, 2026.

The adapter achieves focus with a motor‑driven helicoid inside the adapter that physically moves the mounted Leica M lens forward and backward. Australian Photography summarized the mechanism: “The M2RF achieves focus by moving the mounted Leica M lens forward and backward.” Petapixel published an exploded graphic labeled “Electronic Helical Drive System” showing the circular metallic and black components that make up the drive assembly. The M2RF also includes electronic contacts to transmit EXIF data and, where applicable, supports aperture selection via the camera interface.

Megadap and early reports emphasize Canon Dual Pixel AF compatibility, with support for Eye Detection, Subject Tracking, Face Priority, and continuous AF modes when paired to compatible Canon RF bodies. Australian Photography reported that “according to the company, it is compatible with Canon’s Dual Pixel autofocus system, supporting Eye Detection, Subject Tracking, Face Priority, and continuous autofocus modes.” Imaging‑Resource noted that, “As far as we know, this will be the only autofocus adapter for the Leica M to Canon RF mount” at the time of reporting.

Practical performance caveats accompanied the technical claims. Imaging‑Resource warned that “one downside of converting manual focus glass to autofocus is that the speed and accuracy of the AF will not be comparable with lenses that have built‑in focusing mechanisms... autofocus speed is decent but will suffer from focus hunting and occasionally misfocus. We recommend using AF Single (AF‑S) mode rather than continuous AF (AF‑C) on these adapters to improve accuracy.” Forum users on FredMiranda echoed limitations: JohnDizzo15 noted restricted AF coverage often centered in the frame and field curvature induced by sensor stack differences, calling the adapter “definitely still fun to play with” despite those limits.

Visuals and early leaks accompanied the announcement. Imaging‑Resource reported that the Japanese retailer Shoten Kobo first posted an image of the adapter on X, while Petapixel described the retail photos as a black and silver M2RF shown on a dark background with the logo in white and gold text. Megadap supplied additional images to Australian Photography for the CP+ coverage.

Megadap listed a May release window with pricing to be confirmed. Australian Photography reported, “The Megadap M2RF is scheduled for official release in May, with pricing to be confirmed.” LeicaRumors catalog entries used an alternate label, LM‑CR ME, and community posts on FredMiranda from user Alex Phan circulated a feature list that included claims such as “True Autofocus on ANY Leica M lens” and “Full Canon Dual Pixel AF power,” all presented as user‑reported highlights rather than independent test results.

The M2RF fills a conspicuous gap for RF shooters who want autofocus on classic Leica M and third‑party M glass, but editorial and community voices stress hands‑on testing will be required to confirm AF speed, accuracy, and practical coverage once retail units ship.
