Metabones T Speedbooster CINE XL 0.64x Canon EF - MFT
Boost the performance of your full-frame Canon EF-mount lenses when mounted to your Micro Four Thirds camera with this fifth-generation T CINE Speed Booster XL 0.64x 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 0.64x wider and simultaneously increasing the maximum aperture by about 1-1/3 stop. Further improving on previous generations of Smart Adapters, this fifth-generation model now features a rubber gasket to protect the cameras mount from dust and moisture.
Compatibility
The Speed Booster XL 0.64x is similar to the Blackmagic-specific 0.64x BMCC Speed Booster (MB_SPEF-BMCC-BM1), but has been completely re-designed to meet the following requirements:
The working distance has increased by 1mm to permit use on the Panasonic GH4 and a number of other Micro Four Thirds cameras without touching the flexible outer cover of the cameras shutter mechanism.
The optics are optimized for a standard Micro Four Thirds filter stack thickness of 4mm rather than the 2,4 mm found in Blackmagic cameras.
The image circle diameter has been increased to 21,63mm so that the full 17,3 x 13 mm Four Thirds format is covered. This has been achieved while maintaining unusually high image quality over the 17,4 mm image circle used by the Panasonic GH4 in its Cinema 4k video mode.
Although the Speed Booster XL 0.64x has extra clearance compared to the 0.64x BMCC Speed Booster, there are still a number of Micro Four Thirds cameras that are not supported due to mechanical clearance issues.
