Olympus OM-D E-M10 Mark IV

The Olympus OM-D E-M10 Mark IV is a mirrorless camera introduced in 2020. It is built around the Micro Four Thirds format, and its sensor sits behind a Micro 4/3 mount that takes interchangeable lenses.

At 383 g and 122 x 84 x 49 mm it is a compact, light body for travel or a daily walk. The electronic viewfinder and built-in flash let you frame at eye level and add light without fitting extra accessories.

It suits photographers who want interchangeable lenses in a light body, from travel to everyday shooting. The camera also records 4K video, so one kit covers both stills and movies.

The 20 megapixel CMOS sensor is paired with TruePic VIII processing in a Micro Four Thirds body. That combination gives the camera its core still-image specification in a compact system.

In-body stabilisation counteracts camera shake, so handheld shots at slower shutter speeds come out steadier in dim light. It steadies the camera rather than the subject, which helps most with static scenes such as landscapes, interiors and food.

The maximum burst rate is 15 fps, enough for a short sequence around a fleeting moment, though a maximum figure is not a promise of sustained shooting. The 121 autofocus points give many placement options when you compose.

Sensitivity runs from ISO 200 to 6400, and the top shutter speed is 1/4000 s. Framing comes through an electronic viewfinder with 2,360,000 dots, giving a detailed view of the scene as you line up each shot.

The camera records 4K video, which provides ample resolution for large screens and some latitude to crop or reframe in editing. For travel films and family clips alike, that headroom is useful.

Frame rates reach 60 fps, giving another option for motion and gentle slow-motion playback on a slower timeline. Files record as MPEG-4 or MOV.

A timelapse mode is built in, automating interval shooting for clouds, crowds or any slowly changing scene without needing an external controller.

The tilting screen supports composition from varied angles during video work. For longer takes, a tripod or other support keeps the camera position steady.

The 3-inch TFT LCD carries 1,040,000 dots and responds to touch, giving you another way to operate the camera. The screen also flips to support framing from different angles.

A built-in flash is on hand for a little fill light without extra gear, and the camera also accepts an external flash when you want more power or the option to bounce light off a ceiling.

Wi-Fi and Bluetooth are both built in, so the camera can connect wirelessly to nearby devices.

There is no built-in GPS for automatic location tagging, and no weather sealing, so the body needs shelter from rain and dust rather than tolerating it.

A single SD card slot takes SD, SDHC and SDXC cards with UHS-II support. With only one slot, in-camera backup is unavailable, so copying files after an important shoot matters more than usual.

The BLS-50 battery carries a 360-shot rating. A rating is not a guarantee for every situation, so a charged spare is a sensible precaution for heavy shooting days.

USB charging lets you refill the battery between shoots, which is useful during travel days. Plan longer sessions around a charged spare and breaks for topping up.
