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.

All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.

Sports & Action Professionals — Sony A9 III (2023): A paradigm-shifting camera — the global shutter eliminates every rolling shutter limitation that has constrained action photography for years.
