Canon EF to BMCC Speed Booster Metabones
Kód: AMB_SPEF-BMCC-BM1XPodrobný popis
Unlock the full potential of your Micro Four Thirds camera with our Speed Booster, a cutting-edge accessory designed for both passive and active MFT camcorders/cameras. Elevate your photography with an impressive 1 1/3-stop increase in maximum aperture, achieving a remarkable f/0.80 for exceptional low-light capabilities. Engineered with precision by Caldwell Photographic in the USA, our Speed Booster enhances the Modulation Transfer Function (MTF) for unparalleled image quality, while the 0.64x wider perspective broadens your creative horizons. Enjoy versatile power options, seamlessly integrating with passive devices via an external power source and active devices powered directly by the camera body. The built-in electronics enable effortless lens aperture control, and the detachable tripod foot ensures compatibility with various ball head systems. Please note, we operate independently and are not licensed, approved, or endorsed by Micro Four Thirds or Canon.
Description
Canon EF to BMCC mount Speed BoosterTM adapters designed exclusively for the Blackmagic 2.5k Cinema Camera (BMCC). Note that the new Speed Boosters will only attach to Blackmagic cameras equipped with a Micro-4/3 mount. They cannot be attached to standard Micro 4/3 cameras.
The new 0.64x Speed Booster reduces the full-frame crop factor of the BMCC from 2.39x to 1.53x, thus effectively transforming it into a Super-35 format cine camera. In addition, the speed of any attached lens is increased by 11/3 stops, with a maximum output aperture of f/0.80.

Note:
-
Requires lenses supporting distance information.
-
A third party zoom lens may need to be registered with the Speed Booster/Smart Adapter first in order to detect its maximum aperture.
-
This Speed Booster is designed to cover an BMCC image circle which is not big enough to cover a full-size 36mm x 24mm sensor.
-
For use with fast lenses (faster than f/1.8), the pre-boost apertures will be displayed in the camera.
Slow lenses will report boosted apertures to the camera body but fast lenses will report pre-boost apertures. We won't show f/0.7 with a f/1.2 lens attached, but show f/1.2 instead.
Example:
a) EF 85/1.2L attached, camera display = f/1.2, physical aperture (lens + Speed Booster combined) = f/0.74.
b) Sigma 18-35/1.8 attached, camera display = f/1.0, physical aperture (lens + Speed Booster combined) = f/1.0. -
Some improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster and cause damage to the Speed Booster and/or camera body.
-
Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Speed BoosterTM They need to be modified before they can be safely used on Speed BoosterTM Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster. Scratches and damages caused by rear protrusions on Speed BoosterTM are not covered by warranty.
-
This Speed Booster may NOT be fully compatible with GH4 or other MFT camera. This is use only with BMCC or BMPCC. When Speed Booster® is used with other MFT camera, it may cause damage on the camera.
