Released in 2020, the E-M10 Mark IV sits at the entry level of Olympus's OM-D lineup, built as a genuinely compact, approachable first mirrorless camera aimed squarely at photographers moving up from a phone or a basic compact, rather than the enthusiast and professional bodies higher up the range.

Despite its entry-level positioning, the E-M10 Mark IV retained genuine in-body 5-axis stabilization, a feature some competing entry-level mirrorless cameras from other brands omit entirely to hit a lower price point. It also included a genuinely capable 121-point autofocus system for its price tier, offering meaningfully more coverage than many competing entry-level mirrorless bodies provided at the time. A real value at this price point.
Olympus also gave the E-M10 Mark IV a fully articulating touchscreen aimed at selfie-style shooting and vlogging, a feature not every competing entry-level mirrorless camera of its era included.

Frequently Asked Questions
Is the E-M10 Mark IV a capable camera despite being Olympus's entry-level model?
Yes — its 20.3-megapixel sensor is genuinely close in resolution to Olympus's higher-tier bodies of the same era, and the meaningful differences from the flagship E-M1 line are mostly in autofocus sophistication, build quality and burst speed rather than core image quality or resolution, so image quality itself is not a major compromise.
