Which should you buy?

Portraits, Street & Everyday — Canon RF 50mm f/1.8 STM (2020): The essential first prime for Canon RF shooters — f/1.8 background separation at an accessible price with near-silent STM autofocus.

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.
