Z30vs A7 III
VS
Which should you buy?
Travel & Everyday Video — Z30 (2022): Nikon's lightest Z-mount body — no fuss, excellent subject tracking, and a flip screen for creators.
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.
