Key Features
Allows users to adapt a full-frame Canon EF-mount lens to a Micro Four Thirds Blackmagic Design camera with a Super 16 sensor size, such as the Blackmagic Micro Cinema Camera (BMMCC), Micro Studio Camera 4K (BMMSC 4K), and the original Pocket Cinema Camera HD(BMPCC). It is not compatible with the BMPCC4K Blackmagic Pocket Cinema Camera 4K.
Optics are used with a 0.58x magnification to reduce crop factor from 3.02 to 1.75x and simultaneously improve the maximum aperture by f/0.74.
An advanced optical design with six elements in four groups help improve sharpness and performance of adapted lenses.
Positive-lock lens mount provides extra security when attaching large lenses.
Receives power from the camera body or optional 5 VDC power supply via micro-USB port.
Electronic contacts permit transmission of data between the lens and camera enabling autofocus, autoexposure, image stabilization, iris, and aperture control from the camera body, as well as saving Exif information and more.
Smooth iris support with select Canon (2009 and later), Tamron (SP series 2013 and later), and Sigma (2016 and later) lenses.
Enables electronic manual focusing on lenses, such as the Canon EF 85mm f/1.2L II, that use a focus-by-wire system.
Support for distance and zoom display.
Internal felt flocking prevents reflections.
