Canon and Nikon have joined Sony to form the “big three” in the mirrorless camera wars, but there may be some new competition just around the corner: Leica, Panasonic, and Sigma are reportedly teaming up on a new full-frame camera project.
Leica, Panasonic, and Sigma will be collaborating “closely” on a new full-frame system that’s based on the Leica SL mount. Leica’s SL mount was originally the Leica T mount. But when the Leica SL full-frame mirrorless camera was announced in 2015, Leica renamed the mount the “L mount” and the company now using “TL” for APS-C lenses on the mount and “SL” for full-frame lenses on the mount.
