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.
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.
Compact Travel & Content Creation — A7C (2020): The A7C proves full-frame doesn't have to be bulky. Excellent battery life, reliable Eye AF and a vari-angle screen in a pocketable body is a compelling combination for travel and content creators. The A7C II improved on it, but the original remains a strong value buy.
