Leica M10-R vs Leica M10 Monochrom high-ISO acuity and noise side-by-side comparison
By Onasj (see previous articles by Onansj)
I obtained a customer-release—not pre-release/beta—M10-R and compared it side-by-side with the M10 Monochrom (hereafter referred to as the M10-M) on a test scene at high ISO values. The firmware version for both was the latest firmware currently available to the public: 10.20.27.20 for the M10-R (upgraded from the initial released 10.20.23.49 firmware that was pre-installed in the new camera), and 2.12.8.0 for the M10-M.
Methodology: all shots were taken on a tripod with a 2-second delay to minimize vibration. The same Leica 50 APO lens was used for all tests. The aperture was set to f/5.6 for all tests, at which the resolving power of the 50 APO is about as high as possible among commercially available 35-mm format lenses. The ISO value and shutter speeds were as follows:
