Walking the streets in New York, you see a lot of cameras: iPhones, point and shoots, prosumer Nikons and Canons. I saw a Rollei in the Flatiron on Wednesday and last weekend in Harlem, I saw a girl with a Contax 645 on the street.
The best sighting so far has to be Louis and his workhorse Graflex Speed Graphic. This was taken outside of the Strand on Broadway where you can find him on some weekends. Go talk to him, admire his beast and get your photo taken.
