I held off as long as I could, but the wide angle lens for my new camera really necessitated it.
I’m using it as a camera bag, because the “built-for” camera bags seemed a little too utilitarian/SLR-oriented/compartmentalized for my tastes. Plus I wanted something that was more city-fashionable, something that didn’t scream “I’ve got heavy and expensive camera gear in here!” Thus, man purse.
It’s a Timbuk2 Metro “mini messenger” bag that I picked up at Sports Basement on a whim a few weeks ago. And so far it’s pretty sweet, after I made one modification: removal of the velcro for easier access.
