Metabones Canon EF to Micro Four Thirds T Speed Booster SUPER16 0.58x (for Blackmagic Design Super 16 Cameras) MB_SPEF-M43-BT7

Boost the performance of your full-frame Canon EF-mount lenses when mounted on your Micro Four Thirds camera with this T Lens Adapter from Metabones for Blackmagic Design cameras with Super 16 sensors. This cinema-styled electronic adapter features a positive-lock lens mount that will ensure your adapted lenses are secure, and uses optics to reduce the effects of crop factor by making the lens 0.58x wider and simultaneously increasing the maximum aperture by about 1 2/3 stop.

This adapter is equipped with numerous capabilities thanks to the use of a high-performance processor. The features include support for autofocus as well as the ability to control the iris and aperture from the camera body. Smooth iris effects are possible as well on select lenses, and 5-axis stabilization is available thanks to communication of information with supported lenses. Also, it enables electronic (focus-by-wire) manual focusing, transmits Exif data to the camera, and works with in-lens image stabilization. Additionally, distance and zoom are displayed on certain camcorders and mirrorless cameras, and Cinema EOS lenses are supported when running the adapter off an external 5 VDC power supply via the micro-USB port.

Beyond electronic communication the adapter has many physical advantages, such as black flocking on the inside of the adapter that prevents reflections and a rubber gasket to prevent dust and moisture. For larger lenses, there is a removable Arca-type compatible tripod foot with a 1/4"-20 thread on the base.
