Sony a7 II full frame mirrorless camera

introduction

  • announced Nov 2014
  • who is it for?
    • photographers wanting IBIS in a full frame mirrorless, particularly when using third party lenses such as Canon or Nikon
    • good general purpose stills full frame mirrorless
  • 24mp, similar to the original Sony a7 full frame mirrorless camera but:
    • 5-axis sensor based image stabiliser (IBIS)
    • improved hybrid AF
    • XAVC-S video recording format
    • larger and 25% heavier and thus larger grip
    • now almost entirely magnesium alloy as with the Sony a7S full frame mirrorless camera
    • improved LCD resolution
    • much faster startup time
    • other minor improvements
  • overall it is better for still photography than the Sony a7S full frame mirrorless camera which has the following issues:
    • no IBIS for magnified manual focus
    • no PDAF
    • worse dynamic range, less resolution
    • RAW compression problems

specs

  • same 24mp sensor with PDAF and same same Bionz X processor as the Sony a7 full frame mirrorless camera
    • 25 CDAF points
    • 117 PDAF points
    • excellent RAW dynamic range but not as good as peers for high ISO noise
  • improved hybrid AF but subject tracking in C-AF still an issue
  • 5fps burst
  • shutter 30sec - 1/8000th sec but still loud and no electronic silent mode
  • flash sync 1/250th sec
  • no built-in flash but multi-interface flash shoe
  • exp. compensation ±5 EV
  • ISO 100-25,600 + LOW of 50
  • 5-axis “4.5 stops” (although perhaps more closer to 2.6 stops on tests) sensor based image stabiliser - a 1st on a full frame mirrorless camera, although not as good as the IS on the Olympus OM-D E-M1
    • uniquely, when shooting with a E-mount lens with optical IS, the camera will use the lens OSS for pitch and yaw, while the sensor IS will be used for roll, X,Y axes
    • Sony has previously used a simpler sensor-based IS on 3 of their full frame dSLRs - a900, a850 and a99
  • 3-inch tilting LCD with 1.23 million dots (640×480, RGBW) but not touch sensitive
  • improved 1080 HD video although not as good as on the Sony a7S full frame mirrorless camera
    • 1080 60p 50Mbps XAVC-S video recording format, also 24p
    • S Log2 flat picture profile
    • uncompressed HDMI video out
    • no timelapse recording
  • USB 2.0
  • WiFi + NFC
  • weather sealed
  • 600g
  • 127 x 96 x 60 mm (5 x 3.78 x 2.36″)
  • 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)
