Ronkonkoma, NY—Sigma Corporation launched interchangeable lenses for the Canon EF-M mount digital camera series using APS-C image sensors. The company will gradually introduce the Sigma EF-M mount lenses as members of its Contemporary line.
The EF-M mount models feature a newly and exclusively developed control algorithm. The algorithm optimizes the autofocus drive and maximizes the data transmission speed. In addition, these lenses will work with servo AF (autofocus) and lens aberration correction.
Moreover, Sigma’s EF-M lens range will include its Contemporary line’s set of three prime lenses: the 16mm, 30mm and 56mm. In addition, while retaining the compactness, light weight and image quality concepts of the Contemporary line, the new large-aperture lens series covers from wide to mid-tele angles. It further provides the amount of bokeh and brightness expected from f/1.4 on Canon EF-M mount cameras.
Sigma EF-M Mount Lenses: Key Features
Boasting compact construction, the new lenses will provide image quality that rivals Sigma’s Art line. To achieve the compact form, Sigma based the lens design on the capabilities of the camera body’s functions to correct peripheral light amount and distortion.
What’s more, the combination of an optical design for video AF and the use of a stepping motor enable smooth and quiet autofocus. The lenses will also support the Canon cameras’ face + tracking AF.
Furthermore, the lenses will fully support in-camera aberration correction. This includes corrections for peripheral illumination, chromatic aberrations and distortion. By matching corrections to the optical characteristics of the lens, this function takes image quality to a higher level.
Finally, the lenses are compatible with Sigma’s mount conversion service. This service converts the mount of Sigma lenses to that of a different camera body; thus allowing photographers to continue using their favorite lenses over the long term regardless of camera system. sigmaphoto.com
In the EF-M mount, the Sigma 16mm f/1.4 DC DN C retails for $449; the 30mm f/1.4 DC DN C for $339; and the 56mm f/1.4 DC DN C for $479.
