Firmware update 2.10 in Aug 2016 has introduced a bug that “eats” stars in RAW and JPG astrophoto images when exposure time is 4 secs or longer, or BULB


  • announced Sept 2015
  • 12mp full frame videography oriented mirrorless
  • who is it for?
  • as an upgrade to the Sony a7S full frame mirrorless camera, it adds:
    • now has 164 AF points instead of 25 but no PDAF points
    • can now record 4K footage internally with full pixel read-out
    • Full HD 120 fps video recording
    • 4/5x slow motion recording internally
    • new S-Gamut3.Cine/S-Log3 and S-Gamut3/S-Log3 profiles
    • a new Gamma Display Assist function and improved Zebra function
    • improved performance of Fast Intelligent AF down to EV -4 and is 2x faster in video mode
    • 5 axis sensor based image stabiliser
    • upgraded EVF
    • re-designed buttons
    • lens mount has been further reinforced to ensure greater resilience
    • silent shooting mode can be activated for 5fps continuous shooting and reliability has been enhanced with reduced-vibration shutter movement
    • shutter now rated at 500,000-cycle durability
    • users can now charge the camera via a USB power supply whilst the camera is in operation, thus extending battery life
  • $US2999 RRP


  • 12.2 mp sensor
    • 164 CDAF points
  • no PDAF
  • ISO range of 50 up to 409,600 (100-102,400 native)
  • 5 axis sensor based image stabiliser
  • 5fps burst
  • shutter 30sec - 1/8000th sec but loud
    • electronic first curtain mode, which allows for a quieter shutter, and reduces the potential for 'shutter shock' vibration
    • electronic silent mode also works in 5fps burst mode
  • flash sync 1/250th sec
  • no built-in flash but multi-interface flash shoe
  • exp. compensation ±5 EV
  • Auto ISO usable in manual mode via exposure compensation dial
  • awesome high ISO performance:
  • 3“ tilting 1.23m dot LCD but not touch sensitive
    • 0.78x magnification
    • ZEISS T* Coating
  • awesome video capabilities:
    • excellent high ISO videos
    • 1st full frame camera with full pixel read out in movie mode (ie. no pixel binning) which allows videos with much reduced aliasing, moiré and false color artifacts
    • 4K (QFHD 3840 x 2160 pixels 4:2:2 8-bit) video using the full width of the sensor in the XAVC S format
    • 1080 HD video at 120p at 100Mbps (can give 4-5x slow motion footage internally and can be played back), 60p, 60o, 30p and 24p direct to memory card, and uses full pixel readout without pixel binning
    • video can be cropped to Super 35mm (APS-C) and at this crop can shoot at 120fps
    • S-Log2 gamma for expanded dynamic range
    • XAVC S recording format at 50Mbps in HD video mode in addition to AVCHD and MP4 codecs
    • video mode picture profile that can adjust settings like gamma, black, level and color adjustment
    • time code/user bit
    • various marker and zebra displays on both the LCD screen and viewfinder
    • new S-Gamut3.Cine/S-Log3 and S-Gamut3/S-Log3 profiles (14 stop dynamic range)
    • a new Gamma Display Assist function and improved Zebra function
  • no timelapse recording
  • USB 2.0
  • weather sealed, composite body
  • WiFi with NFC
  • 489g
  • 126.9 x 94.4 x 48.2mm (approx. 5 x 3 3/4 x 1 15/16 in.)
  • NB. does not ship with a proper battery charger, instead it comes with a Micro USB cable and the AC-UUD11 AC Battery Charging Adapter (a USB to AC converter)


  • resolution challenged at only 12mp
  • AF is not great, particularly AF tracking in video mode
  • ergonomics not great
  • range of dedicated E-mount lenses is not great
  • maybe consider a Sony a99 mark II full frame hybrid SLT dSLR instead for video 1)
