The OM System OM-5 Mark II is a mirrorless system camera with a compact physical footprint, measuring 125.3 mm wide, 85.2 mm tall, and 52 mm thick at a weight of 418 g. It features a flip-out 3″ touchscreen with 1037k dots of resolution alongside an electronic viewfinder rated at 2360k dots with 100% coverage, giving flexible framing options across different shooting positions. The body includes a hot shoe for external flash accessories — there is no built-in flash — and carries weather sealing rated for splash protection, with an operating temperature range spanning -10 °C to 40 °C. A tilting viewfinder is not present on this model.
The OM-5 Mark II uses a Micro Four Thirds back-illuminated sensor — notably not a standard CMOS — delivering 20.4 MP of resolution with a native maximum ISO of 6400, expandable to 25600. It accepts Micro Four Thirds lenses and offers 121 focus points with AF tracking, touch autofocus, and manual focus all supported. Sensor-shift image stabilization is rated at 7.5 stops (CIPA) and can be combined with compatible lens-based stabilization for additional effect. The mechanical shutter reaches a fastest speed of 0.000125 s, while the electronic shutter tops out at 3.125E-5 s, and flash sync is available at 0.004 s. Continuous mechanical shooting runs at 10 fps with burst mode support, and exposure times extend up to 60 s. Manual control is comprehensive, covering shutter speed, ISO, exposure, and white balance, and a built-in HDR mode is also available.
The OM-5 Mark II records video at 2160p (4K) up to 30 fps and includes a 24p cinema mode for those who prefer a film-like frame rate. Continuous autofocus remains active during recording, and audio is handled by a built-in dual stereo microphone setup; a dedicated microphone input is also present for connecting an external mic, though there is no 3.5 mm headset jack. Timelapse recording is supported as well.
The OM-5 Mark II is powered by a removable, rechargeable battery with a capacity of 1210 mAh, rated for approximately 310 shots per charge according to CIPA standards. A battery level indicator is built in, allowing users to monitor remaining power during use.
The OM-5 Mark II runs on a TruePic IX processor and supports both RAW capture and pixel shift shooting. Wireless connectivity covers Wi-Fi 4 (802.11n) and Bluetooth 4.2, with smartphone remote control available; NFC and GPS are not included, nor is first-party live streaming support. Physical connectivity includes a USB Type-C port, HDMI output, and an external memory card slot, though the camera has only a single card slot. The hot shoe present on the body is a standard type — an advanced hot shoe is not featured — and there is no advanced hotshoe functionality.
The OM-5 Mark II carries an IP53 Ingress Protection rating, indicating a degree of resistance to dust and water splashing.
