The Sigma MC-11 Mount Converter allows photographers and videographers to seamlessly adapt Sigma Canon EF-mount lenses to Sony E-mount mirrorless camera bodies (including full-frame a7/a9/a1 series and APS-C a6000 series). It delivers native-like electronic performance, fully preserving fast hybrid phase-detection and contrast autofocus, auto-exposure, in-camera lens corrections, and camera-based image stabilization (SteadyShot). The interior is lined with anti-reflective flocking to prevent internal glare, and full EXIF metadata is communicated directly to the camera.
