Tokyo is infested with camera bugs. I can identify three species, at least.

First, there are the genuine camera "nutsos," the kind who heft about 30-cm-long zooms and then bunch up in rows 10 deep to take photos of every single leaf that turns color. The kind that clean the display counters at Yodabashi and Bic with their drool.

Then there is the new breed, those who carry card-size digitals and yank them out suddenly from pockets or purses, like special agents with concealed Glocks.
