Verdictwhich should you buy?

GH7 — Video & Documentary: The GH7 is the GH series at its peak — phase-detect AF finally arrived, alongside 5.7K/60p open-gate, C4K/60p 10-bit 4:2:2, and ProRes RAW. A landmark video camera in the Micro Four Thirds format, and the most complete GH Panasonic has ever built.

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.
