In Tokyo Disneyland/Sea have banned to use Selfie Sticks.Please refer the "5 Reasons Why Selfie Sticks Should be Banned at Disney Theme Parks" URL : http://www.themeparktourist.com/features/20150116/29867/5-reasons-why-disney-should-ban-selfie-stick
Also, many sightseeing areas are thinking same restriction in Japan.Last year, I have been in Kyoto for autumn color season and there were very crowded and many time about 10% of guest stopped and take photo by using a selfie sticks. Then, other people could not pass him/her while they took the shot because of passways were very narrow.
Then, the selfie sticks became selfish bar. Therefore, idea of this product is nice but place to use may be limited.
I used my light weight Lumix G6 which has a fully-articulated rear display that time.
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.
