GearScore™ Verdict — Which should you buy?
Landscape, Wildlife & Professional Studio Photography — D850 (2017): The finest DSLR ever made — 45MP, 9fps, and nearly 2000 shots per charge in a body that still outperforms most mirrorless cameras for battery life.
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.
