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)

firmware updates

  • Nov 2016 firmware 3.30:
    • improving the amount of light at the edge of images taken when using the flash
  • Sept 2016 firmware 3.20:
    • Adds support for the Radio-controlled Lighting System:
      • Sony FA-WRC1M Wireless Radio Commander and Sony FA-WRR1 Wireless Radio Receiver.
  • March 2016 firmware 3.10:
    • Adds Sony G Master lens support
    • Phase-detection AF is supported
    • The lens name will be correctly recorded in the EXIF
    • The AF can be used in movie recording mode with the SEL85F14GM
    • Metabones Smart Adapter IV ($US399)
    • incompatible Canon lenses for fast AF include EF 50mm f/1.8II, 100mm f/2.8 macro, and 135mm f/2L
    • Green mode is the default mode and it is designed to conserve battery power by limiting aperture diaphragm movements and image stabilization. Certain other functions are not available in Green Mode including Auto-Magnify MF Assist and DOF preview
    • Advanced mode.
    • Jan 2017 v0.55:
      • Fix AF accuracy issue.
    • Dec 2016 v0.54:
      • fixed issues with certain Tamron lenses
      • Added an option in Metabones App to enable the use of Digital Zoom in Advanced mode.
      • Stability improvement
    • Nov 2016 v0.53:
      • Easier user interface to select between Green and Advanced mode using Metabones App, with separate settings for newer cameras and older cameras
      • Option to close down the aperture or leave it where it is when camera shuts down
      • Option to let camera body decide whether OIS, IBIS or a combination thereof shall be selected
      • AF accuracy improvement for subjects near infinity.
    • July 2016 v0.52
      • eye AF
      • fast CDAF
      • DMF (direct manual focus) for E-Mount cameras, where the camera switches to MF as soon as AF completes. This is useful for checking AF accuracy when used with focus peaking.
      • Smooth iris
    • Feb 2015, 0.40 for EF-E Smart AdapterTM MARK IV supports 5-axis or 3-axis stabilization including dual-sync IS

reviews

Compared to Canon 6D

  • similar price point
  • 24mp with much better dynamic range and high ISO vs 20mp
  • 1/8000th sec shutter vs 1/4000th sec
  • 5 axis image stabiliser vs OIS only
  • EVF vs mirror + OVF
  • 117 PDAF points vs 11 PDAF points
  • 25 CDAF points vs nil?
  • eye AF vs no eye AF
  • 1200 zone metering vs 63 zone dual layer metering
  • flash sync 1/250th sec vs 1/180th sec
  • 5fps vs 4.5 fps
  • 1.23m dot tilting LCD vs 1mdot fixed LCD (neither offer touch screen)
  • both are splash resistant, both only have USB 2.0
  • 1080HD 60p video vs 1080HD 30p
  • both have WiFi, but 6D also has GPS
  • 600g vs 770g
  • Sony - need to buy Metabones adapter to use Canon lenses, even then 135mm f/2 will not AF
  • Sony - can't use Canon's TTL flash system
  • Sony - no external battery charger
