EOS R100vs Nikon Z8vs 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.
Sports, Wildlife & Hybrid Professionals — Nikon Z8 (2023): Z9 performance in a compact body — 45MP, 8K/60p RAW, and 20fps burst without the bulk or price of the flagship.
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.
