EOS R100vs Leica Q3vs Leica SL3
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.
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.
Professional & Luxury Hybrid Shooters — Leica SL3 (2024): Leica's most capable mirrorless — 60MP, 30fps burst, 8K ProRes, and 7.5-stop IBIS with L-mount's growing lens ecosystem.
