GearScore™ Verdict — Which should you buy?
Professional Sports, Wildlife & High-Resolution Studio Work — A1 II (2025): The most complete camera ever made — 50MP, 30fps, 8K, and the world's best EVF in a single flagship body.
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
