GearScore™ Verdict — Which should you buy?

Landscape, Studio & Professional Stills On L-Mount — Lumix S1 (2019): Built like a tank with one of the finest viewfinders ever made — the S1 is the choice for photographers who prioritise build quality and IBIS over AF speed.

Compact Travel & Content Creation — A7C (2020): The A7C proves full-frame doesn't have to be bulky. Excellent battery life, reliable Eye AF and a vari-angle screen in a pocketable body is a compelling combination for travel and content creators. The A7C II improved on it, but the original remains a strong value buy.
