GearScore™ Verdict — Which should you buy?
High-Resolution Creative & Documentary Shooters — Sigma fp L (2021): 61MP and phase-detect AF in the world's smallest full-frame body — the fp L is the most capable iteration of Sigma's extraordinary compact.
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.
