GH7vs A7 III
GearScore™ Verdict — Which should you buy?
Video & Documentary — GH7 (2024): 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.
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.
