Full Specs available

E-M5 Mark III will be announced on February 28th 2018 with availability in late March/early April. It will launch at 1399 USD/EUR for body-only option.

Here are the full (well, not quite) specs:

  • 16.4 mp stacked CMOS sensor with global electronic shutter
  • TruePic VII image processor
  • Native ISO range: 100-25,600
  • ISO LOW equivalent to ISO 64
  • 12 and 14-bit raw image capture (lossless compression)
  • 4.4 million dot EVF with x0.79 magnification
  • 1 million dots fully articulating display
  • 121-point contrast detect "predictive" AF with new breed of algorithms for scene analysis (different to Panasonic's DFD if you are wondering)
  • 1/32000-60s electronic only shutter (no mechanical shutter) with the usual BULB and LIVE modes available
  • 1/2000s flash sync with every flash and max 1/8000s with FL-900R
  • Sequential High (S-AF) at 20 fps (12-bit capture only)
  • Sequential Low (C-AF) at 11 fps 12-bit and 8 fps 14-bit
  • Pro-Capture mode (max 10 pre-shutter frames)
  • 36 image buffer (raw)
  • HDR RAW capture (3 frames)
  • Multi-exposure RAW capture (3 frames)
  • Improved High Res mode (up to 60 seconds on the long end, up to 50% faster acquisition of individual frames compared to E-M1 Mark II)
  • 5-axis IBIS, up to 6 stops or 6.5 with Sync-IS
  • Auto-levelling function using IBIS
  • 4K video with full sensor readout, up to 30fps
  • Cinema 4K at 24 fps with high bitrate codec
  • Full HD up to 60 fps
  • 720p up to 120fps
  • 8-bit 4:2:2 clean output through HDMI
  • Mic and Headphone jacks
  • USB-C (3.1)
  • Micro HDMI port
  • Single UHS-II memory card slot

In practical terms:

  • The biggest change in regards to IBIS will be improved performance at long exposures, due to increased range of movement (so 1/2 to 4 second exposures with UWAs will be easier to pull off, for example)
  • About 1.3 stop better maximum dynamic range (at ISO 100 vs ISO 200 of other models)
  • About 0.3 stop better tonal range across the board
  • High ISO performance more or less the same as E-M5 Mark II (maybe 1/3 stop better, but nothing you'd normally notice)
