LCD and Viewfinder
Canon A2100 IS 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.
A2100 IS 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 Panasonic Lumix DMC-ZS60 (Lumix DMC-TZ80) (Compare) or Panasonic Lumix DMC-ZS50 (Lumix DMC-TZ70) (Compare).
