EOS R100vs A7Cvs ZV-1 II
Which should you buy?
First Camera / Beginner Photography — EOS R100 (2023): The R100 does the basics well at the lowest possible price point. Its main value is as a gateway into the Canon RF ecosystem — the lenses you buy now will work on any Canon body you upgrade to later. Modest ambitions, reliably met.
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.
Pocket Vlogging — ZV-1 II (2023): The best pocket vlogging camera — 1-inch sensor, ultrawide zoom, flip screen, and real-time Eye AF in a shirt pocket.
