Leica M11vs Leica SL3vs A6400
Which should you buy?
Rangefinder Enthusiasts & Collectors — Leica M11 (2022): 60MP of full-frame resolution in the thinnest digital M ever made — the M11 is the definitive expression of Leica's rangefinder tradition.
Professional & Luxury Hybrid Shooters — Leica SL3 (2024): Leica's most capable mirrorless — 60MP, 30fps burst, 8K ProRes, and 7.5-stop IBIS with L-mount's growing lens ecosystem.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
