GearScore™ Verdict — Which should you buy?
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.
Hybrid & Video — S1 II (2025): The S1 II is the full-frame L-mount hybrid camera Panasonic's system has been waiting for — phase-detect AF, 4K/120p, class-leading IBIS, and a professional build in one complete package. It addresses every weakness of the original S1 and positions Lumix firmly back in the conversation for serious hybrid shooters.
