Here are my three (at least that is what I think today).
U2 Pankow, my entry for the Leica One Challenge last year. I still like this one a lot.

Summicron-M 28mm ASPH at f16, 2 seconds, 160 ISO, Zone focus.
Yellow - purple - red: Detail from a fresco called "the eye". The colours just jump off the screen. Even for a B&W person like my this is bold and fun.

Zeiss Biogon 21mm f2:8 ZM at f4, 1/360 sec, 160 ISO
Metal worker: There is something in the light from the torch and the flying sparks that I like. Tried numerous B&W conversions on this, but keep coming back to the colour version, couldn't make it work the way I wanted in B&W. Shot one morning in January on my way to work.

Summilux 50mm (1st version) at f5.6, 1/180 sec, 640 ISO
