SIGMA 56mm F1.4 DC DN Contemporary for Canon EF-M fatningSIGMA launches interchangeable  lenses for Canon EF-M mount cameras  SIGMA Corporation is pleased to announce the upcoming launch of interchangeable lenses for the Canon EF-M mount digital camera series with APS-C image sensors. SIGMA will gradually introduce the lenses as members of the Contemporary line.  The new Canon EF-M mount models will feature a newly and exclusively developed control algorithm that optimizes the autofocus drive and maximizes the data transmission speed. In addition, these lenses will be compatible with Servo AF and lens aberration correction.   The lineup will include the Contemporary line set of three prime lenses 16mm, 30mm, and 56mm. While retaining the compact, lightweight and outstanding image quality concepts of the Contemporary line, this new large-aperture lens series covering from wide to mid-tele angle provides the amount of bokeh and admirable brightness expected from F1.4 to be enjoyed on Canon EF-M mount cameras. Key features 1. Impressively compact construction with image quality rivaling SIGMA's Art line. To achieve such a compact construction, the lens design is considered based on the capabilities of the camera body function to correct peripheral light amount and distortion. A compactness and lightweight construction combined with superb image quality is achieved.   2. Smooth AF ideal for video shooting The combination of optical design for video AF and use of the stepping motor enables smooth and quiet autofocus. This lens is also compatible with the camera’s Face + Tracking AF.   3. Data loaded for compatibility with in-camera aberration correction The lenses will be fully compatible* with in-camera aberration correction, which 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 an even higher level. *Only when the camera is compatible.   4. Available Mount Conversion Service This service converts the mount of SIGMA lenses to that of a different camera body, allowing photographers to continue using their favorite lenses over the long term regardless of camera system.  Note 1: The Mount Conversion Service is different from a normal repair.
