Firmware update 3.30 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 A workaround for timed shots is to use Continuous Burst Mode but this will reduce dynamic range as it shoots in 12 bit sensor readout not 14 bit 1)

      • 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

    • context-sensitive, 'area-specific noise reduction'
  • focus peaking
  • panorama sweep mode
  • 5fps burst
  • shutter 30sec - 1/8000th sec but is it still loud?
  • silent shutter mode
  • 1st electronic shutter to reduce vibrations
  • flash sync 1/250th sec

firmware updates

  • firmware v3.30 Aug 2016:
    • Adds support for Radio Controlled Lighting System
    • Improves stability for temperature control (temperature rise warning) while taking still images
    • Improves overall stability and operability of the camera
  • firmware 3.20:
    • Allows recording of XAVCS format video with an SDHC card in addition to SDXC card
  • firmware 3.10:
    • Adds support for additional lenses
    • Adds support for Phase-detection AF
    • The AF can be used in movie recording mode with the SEL85F14GM lens
  • firmware 3.00:
    • Improves 4K movie recording time when using the vertical grip (VG-C2EM) or when APS-C/Super35mm mode is activated
    • Improves picture quality
  • firmware 2.00:
    • Adds the selectable feature for uncompressed 14-Bit RAW image capture
    • Adds support to output video via HDMI during use of the Remote Camera Control software (still mode only)
  • firmware 1.00:
    • Reduces the chance of the camera changing to front focus when shooting certain scenes
    • Decreases chroma noise when Long Exposure NR is set to Off
    • Improves continuous shooting at Hi speed so that it can be used just as long when using the flash as without the flash


  • image stabiliser not as effective as dSLR OIS or Olympus sensor based IS
  • LCD screen not touch sensitive
  • loud shutter
  • silent shutter mode limited functionality
  • poor ergonomics - need to resort to menu system too much
  • no timelapse recording
  • no external battery charger bundled - need to charge battery inside camera via USB
  • USB 2.0 only
  • when used with Metabones adapter:
    • Eye-AF and Center Lock-On AF are not possible
    • Face Detection as well as Wide, Center and Flexible Spot Focus Areas work with “compatible” Canon lenses
    • C-AF in video mode is not possible
    • AF is not as good as native FE lenses
    • some Canon lenses are not compatible with CDAF and thus only use PDAF - you need to manually select PDAF mode in the AF System menu 2)

compared to Sony A7II

  • a7R II has higher resolution sensor 42mp vs 24mp
  • better noise, dynamic range, and colour range
  • 399 PDAF points not 117
  • electronic silent shutter mode
  • 4K video not just 1080HD
  • similar weight only 25g heavier
  • faster AF with Metabones adapters for Canon lenses
