The E-M1 III offers essentially the same video output and features as the E-M1 II, which is to say: it makes for an excellent small/light run-and-gun camera, but there are more capable options with better quality capture out there.

Key takeaways:

  • Good quality 4K video + outstanding video image stabilization makes the E-M1 III an excellent run-and-gun option (though no better than the E-M1 II)
  • Decent-quality 1080p footage
  • Minimal rolling shutter
  • Headphone and microphone ports (which occasionally get in the way of the screen)
  • Flat picture profile
  • OM-Log400 profile is 8-bit, not 10-bit like the competition, offering less total dynamic range and flexibility
  • Usable video autofocus with face detect; touchscreen makes for easy tap-to-track


The E-M1 III offers a fairly compelling video package. DCI 'Cinema' 4K/24p footage is plenty-detailed, though it rarely gets near hits the advertised 237Mbps data output in real world shooting. Other cameras in its class offer higher-quality capture (like the X-T4). Still, a Flat picture profile allows for footage that can easily be graded in post. And for added versatility, users can experiment with the OM-Log400 profile. Just note, output is 8-bit, offering comparably less flexibility than the 10-bit log output found in the best of the competition.

Quality + Frame rate Bitrate
DCI 4K/24p Up to 237Mbps
4K/30,25,24p Up to 102Mbps
1080/120,60,50p Up to 50Mbps *
1080/30,25,24p Up to 202Mbps

*1080/120p bitrate is 50Mbps when outputted at 60, 50p

The E-M1 III can also shoot UHD 4K footage at 30, 25 and 24p (up to 102Mbps) and full HD capture at 60 and 50p (up to 50Mbps) as well as at 30, 25 and 24p (up to 202Mbps). For slow-motion work there's a 1080/120p mode that can be output at 60 and 50p footage (up to 50Mbps) or 20, 25 and 24p footage (up to 26Mbps).

In-body image stabilization is where the E-M1 III really shines. You'll have no issues using it for hand-held, run-and-gun style shooting and stabilization is even more effective with digital IS switched on, as long as you don't mind the 1.19x crop this brings.

Video Quality

The E-M1 III's DCI 4K video quality is quite good. It's a little softer than that of its larger sensor peers, such as the X-T4, but not by too much. That being said, it does display the most jagged artifacts of this group. And standard UHD 4K video is far less impressive than cinema 4K and much less detailed than its rivals. HD footage looks a good bit softer than the Fujifilm or Panasonic, but better than that of the Sony.

Rolling Shutter

Resolution and frame rate Shutter rate
DCI 4K 24p 10.9 ms
UHD 30/24p 11.9 ms
FHD 60/30/24p 10.7 ms

Rolling shutter numbers for the E-M1 III are impresively low; essentially, users are unlikely to any rolling shutter impact for most types of video shooting.

Handling notes

The body of the E-M1 III offers 3.5mm microphone and headphone ports that annoyingly get in the way of the articulating screen when in use. The camera's touch display is highly responsive and touch-to-focus/track works with good reliability as long as the scene is not too busy or subject too small. Face detect also works well during video capture and can be especially handy for maintaining focus while vlogging.

The camera also saves exposure/white balance/profile/etc. settings separately between stills and video mode making it seamless to switch back and forth between the two.
