MetabonesNikon G to Micro Four Thirds Speed Booster XL 0.64x MetabonesMB_SPNFG-M43-BM2



 Description

A new Micro-4/3 mount Speed BoosterŪ adapter designed exclusively for the
Panasonic GH4 and other selected Micro Four Thirds cameras (refer to the below
camera compatbility table), with a magnification of 0.64x. The 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.
