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 & Photojournalism Professionals — Canon EOS R3 (2021): The pinnacle of Canon's mirrorless lineup for speed — Eye Control AF and 30fps burst in the most rugged body Canon has ever produced.
Landscape & Studio / High-Resolution — Z7 II (2020): The Z7 II is a landscape and studio camera first, everything else second. 45.7MP with weather sealing and dual card slots is a compelling package. If you need resolution, it delivers. If you don't, the Z6 II is the smarter buy.
