M10vs A6400
GearScore™ Verdict — Which should you buy?
Street & Documentary — M10 (2017): The M10 returned Leica to its roots — thinner, cleaner, and video-free by design. The 24MP sensor is the perfect resolution for a manual-focus rangefinder. The simplified control layout respects the M tradition without digital clutter. A camera for photographers who want to slow down and engage with every frame. One of the most satisfying cameras to use — assuming you have M-mount glass to pair with it.
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.
