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.
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.
Portrait & Wedding Photography — A7 IV (2021): The full-frame portrait benchmark — 33MP, AI Eye AF, and exceptional skin-tone rendering in a pro-grade hybrid body.
