Ronkonkoma, NY—Sigma Corporation of America announced 11 of its Art prime lenses will soon be available in the L mount. The company also launched the Sigma Mount Converter MC-21. The converter allows Sigma SA-mount and Canon EF-mount lenses to work on L-mount camera bodies. The L-mount Art prime lenses also further Sigma’s role in the L Mount Alliance with Leica and Panasonic.
Sigma L-Mount Art Prime Lenses Features
Sigma’s L-mount lineup consists of 11 Art prime lenses for full-frame cameras. They range from 14mm to 135mm. The lineup features high-speed autofocus and full compatibility with AF-C mode, in-camera stabilization and in-camera aberration correction.
In addition, the native L mount permits a more stable feel than using an adapter. The lenses also have a surface treatment to enhance strength; a brass bayonet mount offering durability; and rubber sealing at the connection for dust- and splashproof construction.
The lineup includes the first full-frame F1.8 ultrawide-angle lens: the Sigma 14mm F1.8 DG HSM Art. It has a suggested retail price of $1,599. Several other wide-angle lens are included: the Sigma 20mm F1.4 DG HSM Art ($899); Sigma 24mm F1.4 DG HSM Art ($849); Sigma 28mm F1.4 DG HSM Art ($1,399); and Sigma 35mm F1.4 DG HSM Art ($899).
Also in the L-mount Art line is the Sigma 40mm F1.4 DG HSM Art ($1,399) and the Sigma 50mm F1.4 DG HSM Art ($949), which was redesigned for high megapixel DSLRs. Joining them is the first macro lens in the lineup: the Sigma 70mm F2.8 DG Macro Art ($569).
Rounding out the L-mount Art lens are the Sigma 85mm F1.4 DG HSM Art ($1,199; the “bokeh master,” the Sigma 105mm F1.4 DG HSM Art ($1,599); and the Sigma 135mm F1.5 DG HSM Art ($1,399).
Sigma Mount Converter MC-21
The Sigma MC-21 allows Sigma SA-mount and Canon EF-mount lenses to work on L-mount camera bodies. In addition, the MC-21 increases the number of interchangeable lenses manufactured by Sigma that support the L-mount system by 29 lenses.

The L Mount
Leica Camera developed the L mount under the proviso of providing customers with a future-proof, flexible, robust as well as precise bayonet mount that would fulfill even the most demanding photographic needs.
Moreover, to ensure product diversity, the diameter of 51.6mm was chosen to make the L mount suitable for use not only with full-frame cameras but also on cameras with APS-C sensors. The short register of 20mm also enables a short distance between the lens and the sensor. This in turn permits more compact construction—particularly helpful for developments in the wide-angle lens segment.
In addition, to ensure resistance to extreme stresses, the camera bayonets are manufactured from wear-resistant stainless steel and with four flange segments to prevent canting. The standardized L-mount contact strip also helps ensure trouble-free communication between the electronic components of the lens and the camera, including the possibility of installing future firmware updates.
