Which should you buy?
Sports, Wildlife & Dslr Enthusiasts — Canon EOS 90D (2019): The best APS-C DSLR Canon ever made — 32MP, 10fps, weather sealing, and an optical viewfinder experience no mirrorless can replicate.
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.
Travel, Street & Premium Compact Shooters — Leica Q3 (2023): 60MP, Summilux 28mm, IBIS, and weather sealing — the Q3 is the ultimate fixed-lens camera for those who can justify the cost.
