The Adapter for Sony A/Minolta Mount Lens To Canon EOS M Cameras from Novoflex allows you to use Sony A/Minolta mount lenses on Canon EOS M mirrorless cameras. This will provide you with a broad range of focal length and lens type options to use on your Canon mirrorless camera. This adapter has an integrated aperture control ring and can be used with all Sony A/Minolta mount lenses. This is a completely manual adapter: no electronic information passes from lens to camera, and manual focusing is required. Using the camera's aperture priority mode for exposure metering is suggested.
