EOS R100vs Lumix GH6vs A6400
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.
Video Creators & Documentary Filmmakers — Lumix GH6 (2022): The video-first MFT camera — 5.7K internal, unlimited record times, and 10-bit colour for professional video production.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
