Olympus OM-D E-M10 Mark III

The OM-D E-M10 Mark III is a compact mirrorless camera from 2017 built around the Micro Four Thirds system. At 122 x 84 x 50 mm and 410 g, it is light and easy to carry, and the Micro 4/3 mount accepts matching lenses.

It suits photographers wanting a step up from a phone or compact without the bulk of a larger system. The electronic viewfinder offers 2.36 million dots for composing shots before you press the shutter.

In-body stabilisation helps keep handheld shots steady in dim light, and the flip-out screen makes framing easier at low or high angles.

The 16-megapixel CMOS sensor uses the Micro Four Thirds format, and the TruePic VIII processor handles its output. That resolution provides files suited to prints with room for cropping.

In-body stabilisation is the standout for stills. It counteracts camera shake, so you can use slower shutter speeds handheld and get sharp results in interiors or evening light where you would otherwise raise the ISO.

For action, the camera can shoot bursts at up to 8.6 frames per second and offers 121 autofocus points. The maximum shutter speed of 1/4000 second may limit wide apertures in bright daylight.

The ISO range runs from 200 to 25600. Because stabilisation lets you work at slower shutter speeds, you can often keep sensitivity low in dim interiors instead of pushing the ISO higher when light falls.

The camera records 4K video, which gives plenty of detail for projects that end up online and leaves latitude to crop or reframe a clip during editing.

Frame rates reach up to 60 fps; higher rates suit smoother motion, while lower rates remain the everyday choice for general filming. Recordings are saved in MPEG-4 or MOV formats.

In-body stabilisation helps handheld footage, smoothing the small shakes that make walking shots jarring. It will not steady a subject moving through the frame, but it reduces the need for a tripod or gimbal in everyday filming.

A built-in timelapse mode automates interval shooting, so you can set the camera to capture a sunset or passing clouds without an external intervalometer.

The 3-inch TFT LCD offers 1.04 million dots and touch control. Combined with live view, the screen lets you compose and check the frame before you commit to a shot.

The flip-out screen helps with low and high angles, so you can shoot from ground level or above a crowd while still seeing the frame clearly.

The camera has Wi-Fi for wireless connection, but there is no Bluetooth, and no built-in GPS for automatic location tagging.

A built-in flash covers low-light snapshots, and the camera accepts external flashes for more power and control. The body has no weather sealing, so it needs shelter from rain and spray.

Images record to a single SD, SDHC or SDXC card, and the slot is compatible with faster UHS-II cards too.

With only one slot, there is no second card for in-camera backup, so photographers covering important events should download cards promptly or carry spares.

The BLS-50 battery is rated for 330 shots, though that figure is a baseline rather than a guarantee, and actual endurance varies with settings such as the screen and Wi-Fi. A spare battery makes sense for longer outings.

There is no USB charging, so you cannot top up the battery from a laptop or power bank while travelling.
