At the press conference they quoted $3,500 US dollars. Rollout is set for this Sept.
B/c it was positioned as excellent for movie-making too there were a bunch of accessories that were mentioned that will launch at the same time - several of the accessories (wireless connectivity for tethering, audio capture, a vertical handgrip mount, etc.) seem to be falling roughly in the $400 US dollars range.
They mentioned the cam uses a new “E” mount that will accept a bunch of users’ different lenses - sort of a universal mount to avoid the need for adapters is how it sounded to me.
And, they claimed it provides the 1st real-time Eye AF as part of the movie-making features. (But, keep in mind we saw a bendable tablet from Samsung in their press conf. too & we know what’s transpired since then… As a former tech mktr and CTO (for the small/med biz sector) at a Fortune 20 I know about spin and have a healthy skepticism about features claims until proven in the mkt - as a gadget addict I’ve learned to not jump in and purchase the 1st new tech off the line for my personal use too).
