But having shot with both the K-3 monochrome and the Leica M10 Monochrome, I can vouch that there is definitely a better tonal range from a monochrome sensor compared to converting in post. I really like the idea of a pocketable monochrome camera that doesn't have a Leica price attached to it. The GR IV monochrome is essentially the same camera as the GR IV—same lens, same internals aside from the sensor. The big downside is that the monochrome GR IV costs $2,200, a full $700 more than the color version. It also makes Fender the only major instrument manufacturer that owns its own top-tier recording software.
