Metabones Nikon G to Micro Four Thirds Speed Booster XL 0.64x SKU: MB_SPNFG-m43-BM2 A new Micro-4/3 mount Speed Booster adapter designed exclusively for the Panasonic GH4 and other selected Micro Four Thirds cameras with a magnification of 0.64x. The Metabones Speed Booster XL 0.64x uses an advanced 6-element optical design to achieve extraordinary optical performance at apertures up to an incredible f/0.80, a new record for Micro Four Thirds format. The new Speed Booster XL 0.64x reduces the full-frame crop factor of the Panasonic GH4 from 2.0x to 1.28x, thus effectively transforming these cameras into APS-H format. When the GH4 is used in Cinema 4k video mode the horizontal full frame crop factor is reduced from 2.34x to 1.50x, thus effectively transforming the GH4 into a super-35 format 4k 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 when an f/1.2 lens is used. For example, a 50mm f/1.2 becomes a 32mm f/0.80, which is the fastest aperture available for full size Micro Four Thirds format. Speed Booster XL 0.64x Key Features Industry's best aperture ring covers a 8-stop range, clearly indicating actual number of f-stops.

Metabones Nikon G to BMPCC4K Speed Booster ULTRA 0.71x SKU: MB_SPNFG-m43-BM4 The new Speed Booster ULTRA 0.71x for BMPCC4K uses an advanced 6-element 4-group optical design incorporating ultra-high index tantalum-based optical glass.  The new design is specifically optimized to bring the same level of astonishing performance as the ULTRA Speed Boosters for Micro Four Thirds to users of the Blackmagic Pocket Cinema Camera 4K. In particular, the Speed Booster ULTRA 0.71x is optimized to correctly account for the BMPCC4K camera’s specific filter stack located near the sensor surface. This is especially critical at the extremely large apertures made possible by Speed Booster technology. As a result of this careful optimization, an enormous range of full-frame optics, ranging from vintage film lenses to the latest digital designs, will function flawlessly when adapted to BMPCC4K bodies. The Metabones Speed Booster ULTRA 0.71x reduces the crop factor of the BMPCC4K camera as shown in the above table. The new design for BMPCC4K makes very effective use of exotic materials at the furthest limit of glassmaking technology, and as a result is almost perfectly corrected for use with all full-frame SLR lenses regardless of aperture or exit pupil distance.  The Speed Booster ULTRA 0.71x will also work extremely well with many DX and APS-C format lenses, provided the image circle provided by the lens is large enough. Optical performance of the new Speed Boosters is so good that the MTF of any lens attached to it will be improved. Even the latest generation of ultra-high performance SLR lenses such as the Zeiss Otus series can be improved by adding a Speed Booster ULTRA 0.71x.
