GearScore™ Verdict — Which should you buy?

Everyday, Travel & Events On Fujifilm Or Sony Aps-C — 18-50mm f/2.8 DC DN Contemporary (2021): The lightest f/2.8 standard zoom ever made — 290g is astonishing for a lens of this capability, and it optically over-delivers at the price.

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.
