Verdictwhich should you buy?
EOS M — Canon Mirrorless History & Ef-M Collectors: Canon's first mirrorless — a historic body that broke new ground with touch-AF and EF-M, but its sluggish contrast-detect system quickly became its Achilles heel.
A1 II — Professional Sports, Wildlife & High-Resolution Studio Work: The most complete camera ever made — 50MP, 30fps, 8K, and the world's best EVF in a single flagship body.
