Blackmagic Design has joined the L-Mount Alliance. It did not go unnoticed at yesterday’s launch that the new Full FrameBlackmagic Cinema Camera 6K has an L-Mount.

Andreas Kaufmann, Chairman of the Supervisory Board of Leica Camera AG, texted from Portugal, where Leica Camera is celebrating the 50th anniversary of the factory in Famalicão.

Dr. Kaufmann said, “We’re welcoming our new member in the L-Mount Alliance—Blackmgic Design. With the L-Mount, first shown in the Leica T (Top 701) 2014, photographers and cinematographers have the most versatile choices in lenses ever! Welcome to the club, dear friends at Blackmagic!”

That “club” is known by the companies it keeps. It began with Panasonic and SIGMA, expanded to include Leitz, DJI, Samyang and Astro Design—and now includes Blackmagic Design.

The L-Mount “aims to provide photographers and cinematographers with one unified lens mount standard. Developed by Leica Camera, the L-Mount allows photographers to combine lenses and cameras made by the Alliance partners for a new era of creative freedom.”

L-Mount is a twist-lock bayonet mount, with a 20mm flange focal depth, 51.6mm inside diameter and lens-to-camera communication with metadata.
