L-Mount Alliance
The L-Mount Alliance is a partnership between Leica Camera, SIGMA, Panasonic, Ernst Leitz Wetzlar GmbH, DJI, ASTRODESIGN, SAMYANG and Blackmagic Design. Their aim is to offer photographers a standardised lens mount standard. The L-Mount developed by Leica Camera enables photographers to combine lenses and cameras from the four alliance partners. A new era of creative freedom has begun.
