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 & High-Resolution Studio Work — A1 II (2025): The most complete camera ever made — 50MP, 30fps, 8K, and the world's best EVF in a single flagship body.
