GearScore™ Verdict — Which should you buy?
Commercial, Portrait & Landscape Photographers — GFX 100S (2021): 102MP medium-format with IBIS and phase-detect AF at a price that made serious large-format imaging available to a new generation of photographers.
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.
