GH2 Nikon Speedbooster? Nikkor AI-s for GH2 (lens choice help, clarification)?

Feel like a dummy, but I need clarification on this..


I have what I need for stills shooting, but want to take a stab at video. I have a slew of decent Nikkor AI-s lenses: 28mm, 50mm f1.12, 105mm, really SOLID stuff and I know they're often recommended for DSLR shooters. I don't want to break the bank buying a ton of new lenses..With the crop factor, it seems just a regular Nikon -> MFT adaptor wouldn't get me far - I would be looking at a minimum of 56mm (28x2) in Focal Length, 210mm Max. Of course, I could grab a 20 f1.7 or a Voigtlander, but that's more money, especially the latter. I'm open to that, if the Nikkors won't cut it.


So, can someone explain what FL I would be looking at with the Metabones Nikkor -> MFT speedbooster? Further, would these be good for video on, say, a GH2 or the Black Magic Pocket cam? Seems like if I could work with lenses in the 40mm to 100mm I would be in range for plenty..Thanks a lot!
 
For the GH2 in video mode, your calculation for focal lengths with speed booster is:

Lens focal length x Metabones focal reducer (.71) x GH2 crop factor (1.86 in video mode)

So, 50mm lens x .71 x 1.86 = 66mm
