Review Excerpt

  • Rugged construction; 51-point AF system capable of sophisticated AF tracking; Large, bright optical viewfinder; 7 fps JPEG or 12-bit RAW burst mode; HD Video capture.

  • 14-bit RAW mode slows continuous shooting from 7 fps to 2.7 fps; Somewhat slow AF for a camera at this level, especially in 51-point auto-area mode; Video capture tops out at 720p24.

  • Read our Nikon D300S Full Review

  • Excellent still image quality for its class; Fantastic, highly-detailed video quality; Superior video recording chops with 4K video (both Cinema 4K and Ultra HD); Responsive all-around performer with great AF performance and burst shooting; Rolling shutter is minimal with 60p and 30p video; Splash- and dust-proof magnesium alloy body; Built-in Wi-Fi with NFC.

  • High ISO performance not as good as some APS-C models (IQ drops quickly past ISO 3200); Overall still image quality not significantly better than the GH3; Sluggish buffer clearing with RAW files; Rolling shutter noticeable on 4K video; Not as compact as most mirrorless cameras.
