I’d filed the existence of this thread away.
I now have extensively trialled an M11M.
It locks up the same as the regular version. Leica say that it is operating normally. The extra pixels are useful sometimes; I can travel with just a 50mm instead of a 50 and a 75. A lighter bag is handy, and I can take an 18mm, macro or 135mm depending on what I think I might see.
The M11M metering generally, and the highlight weighted metering specifically, is amazing, and hugely better than the earlier Monochroms. But off-the-sensor metering is problematic with a shuttered camera. When you shoot it closes the shutter then opens to expose. That slows things down.
The Pentax Monochrome is also very interesting. The Sony STARVIS IMX571BQR-J sensor in the regular/colour K-3iii was already offered in a monochrome version, the STARVIS IMX571BLR-J, so it was relatively simple for Pentax to make the K-3iii Monochrome. There is no pre-existing monochrome version of the sensor in the GRIII or the K-1 sensor, so whatever we want, we probably won’t get a monochrome version of those cameras.
Anyway, they all take very nice photos.
