Designed to help users learn about the cameras' features and how to use them on the spot, the "In-Camera Guide" is accessible from the menubutton on the camera and allows users to easily search by purpose or keyword for functions they seek.
They utilize the increasingly-common side menu that can be accessed via a swipe to the right (or button press in the top left corner) and visually seems to appear from under the main inbox screen.
It is an unconscionable truth that many cars now require users to dig through several menu layers to tackle these simple tasks, which used to be blind knob or button-based operations.
And since the pen is connected to your Adobe Creative Cloud account (of course) its button can call up a menu of your color palettes from Kuler, line weights, brush styles or your personal clipboard.
