LCD and Viewfinder
Olympus E-P1 has a Fixed Type 3" LCD screen with a resolution of 230k dots. Both the screen size and the screen resolution is up to the standards of this class.
E-P1 doesn't have a viewfinder and no option for external viewfinder. Lack of a viewfinder can be problematic especially under strong light where visibility of LCD screens goes down dramatically. If you need a Mirrorless camera with a built-in viewfinder in a similar price range, consider Panasonic Lumix DMC-G1 (Compare) or Leica M-E Typ 220 (Compare). If the price is not an issue, take a look at our Top Rated Cameras with Viewfinders.
