Review Excerpt

  • Very fast top frame rate; full-time phase-detect autofocus; Full 60p HD video; Excellent kit lens; Very good high-resolution sensor.

  • Heavy; EVF appears dim when used in bright light; AF tracking in Movie mode was unreliable in our testing.

  • We haven’t finished our review of the Nikon J3, but we have extensive sample photos and a hands-on report.
