    • has no AA filter
    • has no PDAF, only CDAF points
    • is NOT capable of electronic first curtain mode
    • 4fps not 5fps burst
    • flash sync only 1/160th sec not 1/250th sec, which is a bit poor
    • magnesium alloy body not composite
    • really needs to be used on a tripod to make the most of the high resolution sensor
  • who is it for?
    • landscape photographers using a tripod
    • studio photographers using studio flash

specs

  • 36mp sensor with no anti-alias filter
    • 25 CDAF points
      • Eye-AF, which locks the focus on the pupil of faces that are detected
      • Flexible Spot AF (with adjustable focus point sizes)
      • Zone AF
      • Lock-on AF C-AF
    • excellent RAW dynamic range
  • no PDAF
  • Bionz X processor
    • improved sharpening algorithms
    • diffraction reduction software for small apertures
    • context-sensitive, 'area-specific noise reduction'
  • focus peaking
  • panorama sweep mode
  • 4fps burst
  • shutter 30sec - 1/8000th sec but loud and no electronic silent mode and does NOT have electronic first curtain mode, which would have allowed for a quieter shutter, and reduced the potential for 'shutter shock' vibration
  • flash sync 1/160th sec
  • no built-in flash but multi-interface flash shoe
    • Multi-Interface Shoe allows you to connect a latest model Sony flash, an external mic, video lamp, or XLR adapter
  • exp. compensation ±5 EV
  • ISO 100-25,600
  • 3“ tilting 1.23m dot LCD but not touch sensitive
  • XGA EVF

  • no timelapse recording
  • USB 2.0
  • weather sealed, composite body
  • WiFi with NFC
  • 465g
  • 127 x 94 x 48 mm (5 x 3.7 x 1.89″)
  • 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)
  • $2299 body only
  • optional vertical grip & 2nd battery holder ~$300

compared with Nikon D800E

  • same sensor
  • the Nikon allows fast phase detect AF and has a wide range of Nikon AF-S lenses
  • the Sony allows fast phase detect AF only with the extra $350 adapter and the Sony Alpha lenses
  • the Sony allows fast CDAF and Eye-AF with CDAF-compatible lenses (very few currently)
  • the Sony allows manual focus with almost ANY 35mm full frame lens ever made
  • the Sony offers 1080 HD video at 60p not just 30p, and potential for better C-AF
  • the Sony is far smaller, has WiFi/NFC and is $700 cheaper

reviews

    • difficult to shoot with
    • shutter vibration issues giving double images at certain shutter speeds
    • slow AF, not well suited to street photography
    • best suited to still life shots on a tripod with the best quality lenses matched to the sensor
    • EVF not as good as on the Olympus OM-D E-M1 while the image stabiliser, weatherproofing and lens range is sorely missed
    • video quality is poor - poor codec, poor resolution, lots of moire
    • poor ergonomics and mechanical shutter
