I guess it will be a good idea to use 120MP sensor video for the medical purpose in the near future.By using this video through internet, a doctor can support a surgery of another doctor, advising how to from remote place.
I am very interested in the V2 from its function and size point of view.The design is reasonable. If you do not like this design, you have many other choices.
I am a user of EOS-5D and am looking for compact and lens interchangeable one for trip. Among the any mirrorless cameras, I expect the most speedy AF and a full size shot can be retrived from video to V2.
My only concern is the V series have manuan focus control from dial and poor line-up of lens. I hope Nikon will develop new prime lens with manual focus in lens.
