LCD and Viewfinder
Canon S100 has a Fixed Type 3" LCD screen with a resolution of 461k dots. Both the screen size and the screen resolution is up to the standards of this class.
S100 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 Compact camera with a built-in viewfinder in a similar price range, consider Nikon Coolpix P7800 (Compare) or Fujifilm X30 (Compare). If the price is not an issue, take a look at our Top Rated Cameras with Viewfinders.
