LCD and Viewfinder
Olympus TG-820 iHS has a Fixed Type 3″ LCD screen with a resolution of 1,030k dots. Both the screen size and the screen resolution is up to the standards of this class.

Lack of a viewfinder can be problematic especially under strong light where visibility of LCD screens goes down dramatically. If you need a Compact camera with a built-in viewfinder in a similar price range, consider Panasonic Lumix DMC-ZS70 (Lumix DC-TZ90) (Compare) or Nikon Coolpix P7000 (Compare). If the price is not an issue, take a look at our Top Rated Cameras with Viewfinders.
