What's new and how it compares
![]() |
The E-M5 III is essentially an E-M1 II 'lite'. It shares the same stills and video capability, though the the bigger model maintains a significantly faster burst rate with AF and a deeper, more comfortable grip.
Key takeaways
- Uses the latest Olympus 20MP sensor and TruePic VIII processor
- Offers a 50MP high-res mode (tripod only)
- 121-point hybrid AF system with updated algorithms
- A new IS system promises improved performance
- Redesigned top plate mimics that of the E-M1 II
- 2.36M dot OLED EVF has a long eye point for glasses wearers
New sensor, AF system and IS system
The E-M5 III shares the same 20MP Four Thirds sensor and 121-point hybrid AF system as the E-M1 II, compared to the 16MP sensor and 81-point CDAF system of its predecessor. It also inherits the E-M1 II's AF algorithms, though not the machine learning AF mode introduced on the E-M1 X. The image stabilization system has been redesigned to take up less internal space, yet should offer a 0.5 EV improvement over its predecessor, giving it a CIPA rated 5.5 stops of stabilization or 6.5 stops of when using either the M.Zuiko 300mm F4 or 12-100mm F4 Pro.
In our own real-world experience, we find this claim to be pretty spot-on, but we will have a full image-stabilization test of the E-M5 III in the near future and will update the review accordingly.
Body changes

The top plate of the E-M5 III now more closely resembles that of the E-M1 II. The mode dial has been moved and can now easily be accessed with one's thumb and 'bulb' has been added to the dial. A dedicated drive mode button, ISO button and exposure compensation button have also been added to the top.
The camera's rear thumb rest has also been extended slightly, to make it more comfortable. And the rear LCD gains touchpad AF functionality, though the panel is the same. At 414g (14.6oz) with battery and card, the E-M5 II is 12% lighter than its predecessor and 28% lighter than the E-M1 II.
Updated EVF and battery
Olympus has ditched the LCD viewfinder panel in the EVF in favor of an OLED one and increased the eye point, which should make the EVF easier to see if you wear glasses. However the magnification has dropped from 0.74x on the E-M5 II to 0.68x. The battery has also changed, from the BLN-1 to the slightly more compact BLS-50. Despite that, battery life is unchanged.
A Micro USB port allows for in-camera charging (though the camera also ships with a separate charger).

Addition of 4K video
The E-M5 III inherits the same 4K video specs as the E-M1 II including stabilized full-width 4K/30p capture, as well as the wider DCI 4K with a theoretical maximum bitrate of ~237 Mbps. It also offers 1080/120p capture. But like its predecessor, there's a microphone port, but no headphone port.
Faster shooting
The top burst rate with AF is 10 fps using the e-shutter and 6 fps using the mechanical. That's nowhere near the 18 fps burst with AF offered in the sports-focused E-M1 II or E-M1 X but a major bump in speed over the E-M5 II's 5 fps burst with AF. It also offer Pro Capture at 10 fps with AF (30 fps without).

There are quite a few cameras that could be considered competitors, and we narrowed it down to four: the Fujifilm X-T30, Nikon Z50, Panasonic DC-G95 (G90 in many regions) and Sony a6600.
