Is the camera you carry around. That’s one of the reasons why I love rangefinder cameras. They’re tiny and light, compared to SLRs. And the lenses are even smaller and lighter. This combo: the M9-P with the CV 40/1.4 weighs 760 grams. With that you get a full frame camera with a fast and multifunctional lens. It fits in a small bag that I carry over my shoulder on the bike, or you might even put it in your cycling shirt. Of course, the Fuji X100 and Leica X2 are even lighter, but since I don’t have one of these, I try to create a versatile system with a nice setup for every occasion.
