Video testing with the Duo 2, this time with telephoto(!)
(All About Windows Phone)

The method of zooming in on the Duo 2 may be almost identical to on Microsoft`s previous Lumia series of camera phones (albeit in the opposite direction, i.e. swipe down to zoom in, not up!), but the mechanics are different, of course. A dedicated 2x telephoto lens gives genuine optical zoom, even in video capture here, thanks to the discovery that `HDR video` knocks the extra lens out of action! See what you think in the embedded video below.
