Not exactly "ITAH," but today I was out for a walk in Central Park with my Tech V 4x5", shooting handheld, and was approached in two separate incidents by guys with Leica rangefinders (one with his friend shooting a Nikon SLR). They all seemed particularly impressed by the Grafmatic filmholder, and one asked, "Is that a new thing?" I told him they've been around for at least 60 years (probably about as long as he'd been around), and explained their even older ancestor, the bag mag.
