GearScore™ Verdict — Which should you buy?
Travel, Outdoor & Adventure Photography — OM-3 (2024): The ideal mid-range OM System camera — weather sealed, class-leading IBIS, and superb computational features in a compact body.
Entry-Level Mirrorless & Budget E-Mount — A6000 (2014): The Sony that started a generation of E-mount loyalty — 11fps, 24MP, and 179 phase-detect points in a compact body that remained excellent value for nearly a decade.
