GearScore™ Verdict — Which should you buy?

Landscape, Wildlife & Professional Studio Photography — D850 (2017): The finest DSLR ever made — 45MP, 9fps, and nearly 2000 shots per charge in a body that still outperforms most mirrorless cameras for battery life.

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.
