Olympus OM-D E-M5 Mark III


  • announced Sept 2019
  • essentially an E-M5 sized version of the E-M1II (PDAF sensor) but slightly smaller and 12% lighter than the E-M5 II
  • button, dial layout more closely aligned to the E-M1 II
  • 28% lighter than the E-M1II and significantly smaller but does not have the E-M1II's 18fps burst rates or the 2nd SD card slot and uses a different battery
  • much lighter and smaller than the Panasonic G95 which is 536g
  • this could be a perfect jacket pocketable, compact, light, travel camera, especially when mated with compact travel lenses such as:
    • 12mm f/2.0, 17mm f/1.8, 20mm f/1.7 pancake, 25mm f/1.8, 45mm f/1.8, 75mm f/1.8 - although none of these are weathersealed
    • one would need to use the optional grip for larger lenses such as the versatile, high quality 40-150mm f/2.8
  • advantages over the Olympus OM-D E-M1 mark II:
    • smaller, lighter, jacket pocketable and more comfortable for selfie vlogging whilst walking
    • retains the SCENE modes for newbies
    • 120fps for 5x slo-mo in-camera videos at 1080HD (E-M1II currently only does 60p but perhaps may get a firmware update)
  • advantages of the Olympus OM-D E-M1 mark II:
    • built-in grip for better ergonomics with larger lenses (E-M5III requires optional grip)
    • larger, longer life battery
    • 2 SD card slots instead of only one
    • headphone port for video
    • PC sync port for flash
    • EVF has 0.74x magnification not just 0.68x
    • USB 3.0 not USB 2.0
    • better action sports / wildlife AF and burst rate options:
      • 60fps electronic shutter burst mode in S-AF
      • 18fps C-AF electronic shutter burst mode
      • 15fps mechanical shutter in S-AF and 10fps mechanical shutter in C-AF rather than just 6fps
      • in-camera setting of focus limiter to better allow excluding AF on near or far subjects
      • in-camera preset MF
      • 2×2 switch
      • 3 custom modes on PASM dial


  • 20mp sensor same as on the Olympus OM-D E-M1 mark II
  • 121 all cross-point PDAF now allows the E-M5 to AF and track moving subjects
  • TruePicTM VIII image-processing engine
  • IBIS improved by 0.5EV to 5.5EV (6.5EV in Dual IS with compatible lenses with OIS)
  • 10fps AFS burst with C-AF (30fps without AF)
  • 6fps mechanical shutter burst
  • shutter to 1/8000th sec mech and 1/32,000th sec electronic
  • flash sync 1/250th sec
  • 3“ fully articulating 1mdot rear touch screen - can use the touch pad to move the AF frame while tracking a moving subject
  • 50mp sensor-shift HiRes mode
  • further improved weather sealing, now IPX1-rated
  • Cinema 4K 24p Video
  • FullHD 1080p 24-120fps at 120fps you press the INFO button to select a frame rate (eg. 24fps gives lovely 5 x slo-motion in-camera but without audio, and no C-AF)
  • mic port but no headphone port
  • 14 frame Pro Capture of RAW at 10fps AFS burst with C-AF (30fps without AF)
  • anti-flicker mode
  • Auto ISO can be used in manual mode with exposure compensation when shooting stills but not in Movie mode
  • new 2.36mdot EVF - OLED instead of LCD giving more lifelike, higher-contrast view but lower magnification of 0.68x
  • smaller battery (8.7 Wh BLS-50 from the Four Thirds era) giving 310 shots and allows in-camera USB charging
  • additional Art Filters and Bluetooth but seems it is still only USB 2.0??
  • WiFi Smartphone remote control
  • refined grip and a retooled mode dial
  • unlike the E-M1 II it retains the Scene modes of its pre-decessors
  • single UHS-II compatible SD card slot
  • 414 g (0.91 lb / 14.60 oz) incl. battery
  • 125 x 85 x 50 mm (4.92 x 3.35 x 1.97″)
  • comes with a nice, compact, weathersealed, tilt-swivel bounce flash (FL-LM3)
  • $US1199 body only
  • opt. ECG-5 external grip

Firmware updates
