GearScore™ Verdict — Which should you buy?
Casual & Vlogging — EOS M50 (2018): The EOS M50 is the most complete-feeling entry-level EF-M camera — built-in EVF, fully articulating screen, Dual Pixel AF, and a well-designed compact body. Its 4K video carries a significant crop and loses Dual Pixel AF, making 1080p the practical option — but for stills and casual video, it remains an excellent used-market buy.
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.
