GearScore™ Verdict — Which should you buy?
Entry To Full-Frame Mirrorless & Rf Lens Exploration — EOS R (2018): The RF mount's founding camera — 30MP, Dual Pixel CMOS AF, and the proof-of-concept that launched Canon's mirrorless era.
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.
