• 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

• Nov 2020:
  • adds:
    • improved image stabilization performance while shooting video especially during panning
