Z6 IIIvs A7 III
GearScore™ Verdict — Which should you buy?
Hybrid Video & Action — Z6 III (2024): Partial-stacked FF sensor for near-zero blackout, 6K RAW video, and 60fps burst — Nikon's most capable hybrid.
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.

Z6 III (2024)
- Hybrid photographers who want partially-stacked sensor speed with full-frame quality
