LCD and Viewfinder
Olympus E-PM1 has a Fixed Type 3″ LCD screen with a resolution of 460k dots. Both the screen size and the screen resolution is up to the standards of this class.
E-PM1 doesn't have a built-in viewfinder but an optional external viewfinder is available. 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 Olympus OM-D E-M10 II (Compare) or Panasonic Lumix DMC-GX85 (Lumix DMC-GX80 / Lumix DMC-GX7 Mark II) (Compare). If the price is not an issue, take a look at our Top Rated Cameras with Viewfinders.
