The Adapter for T2 Mount Lens to Canon EOS M Cameras from Novoflex allows you to use T2 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 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.
