GearScore™ Verdict — 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.
Landscape, Wildlife & Professional Studio Photography — D850 (2017): The finest DSLR ever made — 45MP, 9fps, and nearly 2000 shots per charge in a body that still outperforms most mirrorless cameras for battery life.
