In 2018, Leica, Sigma, and Panasonic formed an alliance that would allow the latter two companies to develop products utilizing Leica’s L-mount standard.

Today, Sigma has announced that it will be releasing 11 of its highly-regarded Art prime lenses for the L-Mount and a new lens adapter.

Below are the 11 Sigma Art lenses coming to L mount.

• Sigma 14mm f/1.8 DG HSM Art
• Sigma 20mm f/1.4 DG HSM Art
• Sigma 24mm f/1.4 DG HSM Art
• Sigma 28mm f/1.4 DG HSM Art
• Sigma 35mm f/1.4 DG HSM Art
• Sigma 40mm f/1.4 DG HSM Art
• Sigma 50mm f/1.4 DG HSM Art
• Sigma 70mm f/2.8 DG Macro Art
• Sigma 85mm f/1.4 DG HSM Art
• Sigma 105mm f/1.4 DG HSM Art
• Sigma 135mm f/1.5 DG HSM Art

Each of the 11 Sigma Art L-mount lenses will feature a brass bayonet mount and rubber sealing for weather resistance.

In addition to this series of 11 lenses, new MC-21 Mount Converter Lens Adapters are on their way that will allow the use of select Canon EF and Sigma SA-mount glass on L-mount camera bodies. In total, there are currently 29 Sigma lenses that will be available to use with the converter.

A huge announcement for those interested in the latest L-mount releases, as well as those invested in Leica’s existing system.

While AF-S autofocus will be possible through MC-21, AF-C continuous autofocus will not work. The mount converter also has lens data pre-loaded to optimize all combinations of lens to camera body. EXIF data is also transmitted through the adapter.

The MC-21 mount converter features an LED to notify the user of its compatibility status, on/off state, and when there is a new lens firmware available. It also has a tripod mount to use for lenses that do not already have one built in.

While we know the current prices for the 11 Sigma Art lenses on other mounts, the exact pricing and availability details for the L-Mount versions and the MC-21 adapter will be revealed at a later date closer to the official launch.
