LCD and Viewfinder
Panasonic ZR3 has a Fixed Type 2.7" LCD screen with a resolution of 230k dots. At only 2.7", the screen is on the smaller side and 230kdot resolution is lower than most of the recent models in this class.
ZR3 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-ZS70 (Lumix DC-TZ90) (Compare) or Panasonic Lumix DMC-ZS60 (Lumix DMC-TZ80) (Compare). If the price is not an issue, take a look at our Top Rated Cameras with Viewfinders.
