Verdictwhich should you buy?
Z6 III — Hybrid Video & Action: Partial-stacked FF sensor for near-zero blackout, 6K RAW video, and 60fps burst — Nikon's most capable hybrid.
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.
