M10vs A7R
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.
Studio, Tripod Landscape & Camera History — A7R (2013): The world's first 36MP full-frame mirrorless — a landmark camera that launched the A7R series, despite contrast-detect AF and significant shutter shock limitations.
