About Metabones MB_SPNFG-BMPCC-BM1

The Metabones Nikon G to BMPCC Micro 4/3 Speed Booster allows a Nikon G lens to be mounted to a Pocket Cinema Camera and in doing so, increases the angle of view and the maximum aperture.

The 6-element optical design within the Speed Booster incorporates ultra-high index glass to achieve ideal optical performance at the largest apertures. It increases the maximum aperture by 1 2/3 stops with a maximum aperture of f/0.74 and reduces the crop factor from 2.88x to 1.75x.

The Speed Booster not only increases the field of view and lens speed, it also increases the lens' MTF, or how faithfully the lens transfers detail from the object to the camera sensor. These increases in MTF are seen in the corners as well as the center of the images.

Built into the Speed Booster is a clickless aperture ring, a must-have feature for cinematographers, as well as a removable Arca-type compatible tripod mount.

This Speed Booster is not compatible with the Nikkor 2.1cm f/4.0 lens, or the 20mm f/2.8 AI-S lens.

Metabones MB_SPNFG-BMPCC-BM1 Reviews

I love it!


from Minneapolis, MN

Such a great product. Yes, it's a very tight fit, but that doesn't have to be a bad thing does it? I'd prefer a tighter fit rather than a loose one. Perhaps the other reviewer received a faulty model. Makes beautiful images AND reduces the crop factor on my BMPCC. This purchase was a no-brainer :)


Needed accessory


from Fremont, CA

I own a BMCC and when the pocket cam went on sale I purchased one. The almost 3X crop on the pocket cam is cool for telephoto shots but makes your lens selection much more limited for wide angle. That's where the metabones comes in. Now I rarely use my BMCC and almost always opt for the pocket cam/metabones combo. I willy infrequently shoot with a micro 4/3 lens but almost always use the metabones.

Purchased BMPCC and metabones speedbooster, on my first attempt to install the unit was so tight barely turned, contacted Metabones and was tole this is normal and to fully rotate the speedbooster until the unit locked. well it locked so well it wont come off the camera and rotates about 1/2 an inch. contacted Metabones their answer ship to them in Hong Kong t MY EXPENSE $124. contacted Adorama and since I was under their 30 day return policy customer service issued a return shipping label and returned for exchange that was seven days ago and I'm still waiting with an upcoming event. If only exchanges went as well as sales...
