Which should you buy?
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.
Landscape, Architecture & Astrophotography — Tamron 17-28mm f/2.8 Di III RXD (2019): The compact f/2.8 ultra-wide for Sony FE — lightweight, weather-sealed, and optically excellent at a fraction of Sony's own G-Master price.
