Type: Enthusiast-level and semi-professional interchangeable lens digital mirrorless camera with Micro Four Thirds System bayonet lens mount.

Focusing: Automatic ‘Cross Quad Pixel AF’ hybrid system using contrast-detection and phase-difference detection measurements via the imaging sensor with 1053 X-type focusing points for each. Sampling at 120fps with 100% scene coverage vertically and horizontally. Focus points may be selected manually or automatically by the camera. Area modes are Single, Small (3x), Medium (9x7), Large (15x11), Cross (9 points horizontally, 7 vertically), or Custom shape/size (up to four). ‘Intelligent Subject Detection AF’ tracking modes for humans, dogs, cats, birds, motorsport (cars and motorcycles), aircraft and trains. ‘Starry Sky’ AF mode. Manual switching between one-shot and continuous AF modes. Face/eye detection and auto tracking with adjustable sensitivity (five steps). Continuous manual override available with single-shot mode. In-camera AF limiter (three settings). Low light sensitivity down to -8.0 EV at f/1.2 and ISO 100 (EV 5.5 at f/2.8). Low light/contrast assist via built-in illuminators. Focus assist via magnified image (3x/5x/7x/10x/14x) and focus peaking display (Red, Yellow, White or Black; High, Normal or Low intensity).

Metering: 324-point ‘Digital ESP’ (i.e. multizone), centre-weighted average, spot (2.0%) with highlight/shadow bias, and TTL flash. Spot metering can be linked to AF target. Metering range is EV -2.0 to 20 (f/2.8 and ISO 100).

Exposure Modes: Continuously-variable program with shift, shutter-priority auto, aperture-priority auto, metered manual, TTL auto flash and TTL flash.

Shutter: Electronic, vertical travel, metal blades, 60-1/8000 second plus B (up to 30 minutes). Flash sync up to 1/250 second. Sensor shutter has a speed range of 60-1/32,000 second with flash sync up to 1/50 second. Electronic first curtain shutter has a speed range of 60-1/320 second. Exposure compensation up to +/-5.0 EV in 1/3, 1/2 or full stop increments.

Viewfinder: OLED EVF with 5.76 million dots resolution, 100% coverage and 0.83x magnification (35mm equivalent). 120fps refresh rate. Adjustable for brightness and colour balance plus ‘Simulated OVF’ and ‘Night View’ modes. Anti-fogging coating on the eyepiece. 7.62cm LCD TFT monitor panel with 1.62 million dots resolution, tilt/swing adjustments and touchscreen controls. Adjustable for brightness and colour balance. Auto/manual switching between EVF and monitor screen.

Flash: No built-in flash. External flash units connect via hotshoe or PC terminal.

Additional Features: Magnesium alloy bodyshell sealed against dust and moisture (up to IP53 standard) and with insulation for operation down to -10 degrees Celsius, AE/AF lock, auto exposure bracketing (over three, five or seven frames), depth-of-field preview, programmable self-timer (2 and 12 second delays, 1 to 10 frames, variable interval times), audible signals, auto power-off timer, hard-wired remote triggering.
