Polaroid Impulse AutoFocus lens mount_Leica Thread Mount 4x teleconverter for select SigmaThe Polaroid Impulse is an instant camera that shoots Polaroid 600 type film. This is the fancy Impulse, with autofocus wow! Also, a pop up flash and the usual exposure compensation control. This Impulse is battleship grey, a good reminder that not everything from the 90s was neon. People were boring then, too! Includes case and original box.
