Do you need the still abilities of the Nikon? Something like the Ursa mini-EF would give you better video over the Nikon's AVC. Also the Ursa is pretty much shooting the Nikon in still mode continuously at 30fps, so you could just use single frame stills when you need them. The bitrate ranges from 2.5Gbs-4K down to 44Mbs HD. At the lowest setting the Ursa records at 2x the HD bitrate of the Nikon AVCHD.
Thanks for those suggestions. I already have a Nikon and several lenses and was considering an upgrade.
I took a look at the Ursa mini, didn't know anything about it, and besides the added price of it, beyond my range, I'm looking for something smaller, easier to toss in a bag, carry around, a Nikon upgrade makes sense. The Ursa is probably more camera than I need.
Of course, if I wait, maybe next year Nikon will roll out a 4k DSLR.
I have a D800 and it's great. Not primarily shooting video with it, need easy 'UI' access to photo-related controls, have significant cabinet of Nikkor lenses, and would hate to be using a video form-factor camera for my (majority) outdoor stills.
Not to say the BM isn't a wonderful device for it's purpose ;-) !
