Boost the performance of your full-frame or APS-C Canon EF-mount lenses when mounted to your Micro Four Thirds camera with this fifth-generation T CINE Speed Booster ULTRA 0.71x from Metabones. This cinema-styled electronic adapter features a positive-lock lens mount that will ensure that your adapted lenses are secure and uses optics to reduce the effects of crop factor by making the lens 0.71x wider and simultaneously increasing the maximum aperture by about 1 stop. Further improving on previous generations of Smart Adapters, this fifth-generation model now features a rubber gasket to protect the camera's mount from dust and moisture. 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 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 is 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 as well, such as a black felt flocking on the inside of the adapter that prevents reflections.
