GearScore™ Verdict — Which should you buy?
First Camera / Beginner Photography — EOS R100 (2023): The R100 does the basics well at the lowest possible price point. Its main value is as a gateway into the Canon RF ecosystem — the lenses you buy now will work on any Canon body you upgrade to later. Modest ambitions, reliably met.
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.
