GearScore™ Verdict — Which should you buy?
Travel & Landscape — OM-D E-M5 Mark II (2015): The E-M5 II was the benchmark weather-sealed travel camera of its generation. The 16MP sensor is modest by today's standards but excellent in practice, and the 5-axis IBIS is genuinely useful. Weather sealing, a flip screen, and a high-res composite mode make it a practical companion. A highly capable used-market buy for travel and outdoor photographers who don't need the latest resolution numbers.
Studio, Landscape And Commercial Photographers Needing Maximum Resolution — A7R VI (2025): The A7R VI cements its place as the resolution flagship of the Sony full-frame range — 61MP, AI-driven autofocus, and 8K video make it as capable for video and action work as it is for studio and landscape photography. The price reflects its position at the top of the lineup, but the capability is hard to match.
