When it comes to choosing between two used cameras, the decision can feel like a tug-of-war between performance, features, and value. In my case, the choice is between the full-frame Canon RP, priced at $570, and the APS-C Canon R100, available for just $230. While both cameras belong to Canon’s RF ecosystem, they cater to vastly different needs, making this comparison a blend of technical trade-offs and practical considerations. The Canon RP, launched as an entry-level full-frame mirrorless camera, marked a significant moment for affordable full-frame photography.
