Probably better to post this in the Cinematography section. I'm sure an admin will move it soon.
In answer to your question...
First off the BMCC does not auto focus with any lens. It "might" be possible in the future with EF lenses but its not been stated or implied by Blackmagic.
Onto Nikon lenses. Most of my lenses are Nikon mount. They all work just fine on the BMCC. When using G type lenses I use the Novoflex adaptor and the manual aperture control is perfectly usable. Granted you can't tell exactly what F stop you are on but if that is really that important to you then the G type lenses are really not what you wanna be using.
There is currently no adaptor available that converts the electronics on the EF mount to work with the electronics on a Nikon mount. Not that it would be of much use as the G type lenses have a mechanical aperture that is controlled by a lever in the Nikon body. Not electronically like the EF lenses. This is how the Novoflex adapter (and others) is able to work.
