Verdictwhich should you buy?

A1 — Professional Sport, Wildlife, Portrait & Hybrid Shooting: 50MP, 30fps, 8K — the Sony A1 is the most complete professional camera ever made.

A7 III — All-Round Photography & Video: 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.
