At the heart of this package is the speed booster. Using the Metabones Speed Booster mounted between a mirrorless camera and a SLR lens, Speed Boosterģ increases maximum aperture (hence its name), increases MTF and makes lens wider. This enables the GH4 to be able to use Nikon mount lenses, improving the f/stop and reducing crop factor of an already outstanding set of lenses and providing exceptional image and video quality.

Also included are two Sigma Art lenses (Nikon mount) as shown below Ė NOTE!! when used with a speed booster the AF and OIS will not be available Ė manual focus and aperture;

Iíve also included a third lens I used when I needed a lightweight walk-around-lens, one with autofocus needs, the Olympus lens, also detailed below.

Iím also including a lot of batteries and an extra charger, and normal Nikon-to-MFT adapter.

Highlights of Speed Booster and Normal Adapter

The two adapters provide an amazing range of focal lengths to play with. Because of the 2x crop factor of MFT sensors, the lens focal length is different based on whether you are using a straight adapter (2x for MFT), or the speed booster adapter (0.71x), and also which mode you are in (UHD, HD, or HD with Extended Teleconversion). For example:

With just the Sigma 18-35mm - when you want wide and fast, the speed booster effectively makes your MFT GH4 sensor a Super 35mm. Here are your effective focal lengths in the different modes when using the speed booster:

26mm-50mm in 1080;
28mm-55mm in 4K,
33mm-65mm in 1080 with ETC
and when you want to go long Ė the native adapter will not reduce the crop factor Ė your focal lengths with the same lens will effectively be:

36mm-70mm in 1080;
40mm-77mm in 4K,
47mm-91mm with 1080 with ETC
With the Sigma 70-200mm lens, you are at:

99mm-284mm in 1080 with the SB
109mm-312mm in 4K with SB
129mm-369mm in 1080 with SB and with ETC
140mm-400mm in 1080 with Adapter
154mm-440mm in 4K with Adapter
182mm-520mm in 1080 with Adapter and with ETC
Since all three lenses are fast, fixed aperture lenses to begin with, the two Sigma lenses alone will replace an entire set of prime lenses.
