With either the BlackMagic Pocket Cinema or Micro Four Thirds cameras, you can always benefit from faster aperture lenses and wider field of views. Here's the latest lens adapter release from FotoDiox. The new Fotodiox Excell +1 adapter is similar to other Focal Reducer (Boosted) adapters that will give you a wider field of view and a faster aperture with Nikon or Canon FD Lenses. Right now it's only available for Micro Four Thirds mount which include the new GH4 or BlackMagic Pocket Cinema camera.
According to the Fotodiox deal, if you order between now and July 22nd to get your own Excell + 1 Lens Adapter and FREE Light Cannon Creative Adapter (available only while supplies last). Find out more information following the link (click here).
[Note] In the field of view test, some of the images may appear soft, this is not the fault of the camera. The Rokinon 85mm on a BMPC will be at an approximate 240mm focal distance, and with a Variable ND filter on the lens, things go soft. It's best to use good quality static ND Filters.
In other parts of the video a Canon 70-200mm F/2.8 was used throwing it somewhere close to the 600mm focal range. Since an ND Filter was not used, results were much sharper from the BlackMagic Pocket Cinema Camera.
Judging from the distance of the 5D Mark II, the tripod was quite a distance away. Using the Rokinon 35mm and 85mm lenses, you can tell there is quite a crop factor to the smaller BMPC - more than you would get from a GH3. The BMPC has even more crop than from the original BlackMagic Cinema Camera. That's something to keep in mind if you plan to work in tight spaces. Invest in the right glass, or look for a Speed Booster / Focal Reducer (found here on eBay).
