It might seem strange to buy a camera that can only shoot black-and-white when you can take the output of a color sensor and convert it to black and white afterward. 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.
