LCD and Viewfinder
Nikon 1 J4 has a Fixed Type 3″ LCD screen with a resolution of 1,037k dots. Both the screen size and the screen resolution is up to the standards of this class.
LCD is Touch screen type, so you can change the settings and set the focus point with your fingertips.
1 J4 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 Hasselblad X1D (Compare) or Panasonic Lumix DMC-G85 (Lumix DMC-G80) (Compare). If the price is not an issue, take a look at our Top Rated Cameras with Viewfinders.
