One of the greats. Love the haptics, and short throw focus works well for grab shots. Indestructible little mother, survived a year as primary traveling lens in rural China. Liked it enough that I stockpiled an extra copy -- when discontinued they were being unloaded for under $200 in Asia. Originally badmouthed because it wasn't thin enough to suit some to be called a "pancake" lens and because the "classic" version focused .2' closer. Never hear or see much said about it, I thought it was my secret.
P.S. Almost forgot to include standard troll: digital sucks.
