Blackbird, fly or simply BBF is the name of a twin lens reflex camera which was introduced in the Superheadz Magic camera tour 2008. It's designed by Powershovel as a camera for the advanced lomographer. It is focusable, has apertures f11 (sunny) and f7 (cloudy), and a switch to choose between moment (1/125) and bulb mode of the shutter. It has also a hot shoe to connect a flashgun. It takes 35mm film and is available in a number of different colours including orange, red, blue, black, white and yellow. Its innovative aspect is a set of masks which can be put into the camera before inserting a film. Thus different framesizes are achieveable, from 24x24mm to a size which includes the 35mm film's sprocket holes.
