Luis, a funny coincidence. I have been seriously considering about buying an M8 or M8.2 for b&w tool. The prices are quite reasonable nowadays, and I enjoy rangefinder experience over DSLR or mirrorless any time. The IR sensitivity makes it great for b&w.
However, the quirks and frustration make me think of replacing the Sigma with M9, which would be ok for color also. The price is steep, but it has been my grail for a long time. Usually Sigma images have that unique glow, and then I get banding, noise, low battery, need for a tripod etc. I just can't make up my mind.
