Canon EF to BMPCC T Speed BoosterTM adapters designed exclusively for the Blackmagic Pocket Cinema Camera (BMPCC). Note that this new 0.58x Speed Booster will only attach to BMPCC equipped with a Micro-4/3 mount. They cannot be attached to standard Micro 4/3 cameras (cannot be attached to GH4, GH3, GH2 and GH1 body).
The new 0.58x Speed Booster reduces the crop factor of the BMPCC from 3.02x to 1.75x and produces the largest aperture optics currently available, with a maximum output aperture of f/0.74.
Here are a few examples:
