edit: for now, main google results are "how to disable haptic feedback on iphone 7" -- huh?
edit 2: ok, found some basic info: http://appleinsider.com/articles/16/09/27/inside-the-iphone-...
So, from what I understand, still a buzzer, only much more precise, controllable and subtle (?). Still not clear if the Kodak's gonna be the same, or something more interesting.
edit 3: eh, based on http://www.trustedreviews.com/kodak-ektra-review, I believe it's just a buzzer in Kodak too: "There’s a little bit of haptic feedback as you rotate the dial to give it some tangibility." So, nothing to write home about, I think.
