As the motivation to use M/LTM lenses increases, the value proposition of Leica digital M cameras increases. In other words, digital Leica M's are an extreme example of a value-added product. People pay for value(s) unique to the digital M platform. The market has spoken. Digital M cameras are worth it.
Objective technical performance (analog and raw file signal-to-noise ratio) is a limited metric. For instance, camera SNR comparisons ignore the role of lenses. But they are useful since aesthetic (subjective) image rendering depends on SNR.[1] This becomes relevant when sensor underexposure is unavoidable. Hand-held usage in low light or shadow region rendering in bright or normal light are the most common situations where SNR becomes important.
In terms of objective technical performance, I consider the M10 to have no disadvantages compared to its most recent 24 X 36 mm sensor competitors. For many people the M-240 platform's performance level is sufficient. It is only about 2/3 EV below the M10 and about 1 EV below the M-246. The M-246 out performs almost all other 24 X 36 sensor cameras and is not bested by the others.
1. Subjective, perceived image rendering preferences are obvious when the SNR is very high. But when the SNR is low those same characteristics are compromised by noise. An extreme example would be a low SNR of 2:1. Compared to a SNR of 200:1, differences in lens resolution, micro-contrast, file curvature, etc. are obscured by the a 100-fold increase in the uncertainty of the data (raw-file, photon-count estimates for each pixel).
