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 & Video — A6700 (2023): Best-in-class autofocus and 4K/120p video in a compact APS-C body — the standout camera under £1,000.
