Menus: About the touch screen
The viewfinder (VF) is a 720p touch screen for some functions.
Because this is the only screen use it sparingly as a touch screen. Don't
use the touch screen to scroll through menus!
Use the touch screen for auto focus (see section on focusing).
Otherwise, I recommend keeping your fingers off the screen!
If the screen becomes dirty, it can be cleaned only with a microfiber
cloth. If it is smudged, turn the camera off and clean the LCD screen
with a very slightly damp microfiber cloth (water only). Wait until it
dries before turning on the camera.
