Recently, Novoflex has launched SL – EOS electronic adapter so that the users can use ‘around 30’ Canon EF lenses with the Leica SL camera. The adapter transmits focal distance and aperture EXIF data. Also, the adapter has an AF/MF mode, and supports autofocus, aperture control, and depth of field indication. However, the adapters can work fine with ‘around 30’ Canon EF lenses and teleconverters image stabilization is not supported.
You can get this SL-EOS adapter on Novoflex’s website for $555.
