Verdict

The Olympus OM-D E-M10 Mark IVGo to product viewer dialogue for this item. is a compact, retro-styled mirrorless camera featuring a 20.3MP Live MOS sensor and the TruePic VIII image processor. Its standout characteristics include a highly effective 5-axis in-body image stabilisation system providing up to 4.5 stops of compensation, 4K/30p video recording, and a 3-inch 180° flip-down touchscreen ideal for selfies. Key pros are its lightweight, portable design (approx. 383g), excellent JPEG colour reproduction, and beginner-friendly modes like Live Composite. Main cons include a contrast-detect autofocus system that can struggle with fast-moving subjects, the lack of an external microphone jack for video, and the absence of weather-sealing.
