One of M43's most appealing features is that it weighs less than competing formats...potentially, a lot less. But where, exactly, do you value light weight? around the neck? in the hand? in a shoulder bag? on a belt pouch? somewhere else? For my part, I find it liberating to be able to carry 1 body and 3 or 4 lenses in a belt pouch. I also find it liberating to take a long walk while wearing around my neck a high-quality camera that weighs only 0.5 to 0.8 kg, depending on the lens. Do you see what I'm getting at? Some of us are concerned with how easily we can hold one camera in two hands. Others don't care if the camera+lens is heavy, as long as the second, third, and fourth lenses will add little additional weight. Others might say, "With a lightweight camera/lens, I can get by with a lighter tripod and quick release." Or "When my entire travel kit weighs less, my camera bag, in turn, can weight less." Why, or where, do YOU appreciate M43's light weight?
