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.
Professional Sports, Wildlife & Photojournalism — A9 II (2019): The A9 II polished the A9's groundbreaking formula — 20fps blackout-free, improved subject tracking, and a LAN port made it the professional sports standard.
