The Duaflex line of Kodak cameras was introduced in 1947 for the modest price of $17.25, which in 2010 equates to $166. This Duaflex is the model II, which didn’t hit the market until 1950. The Duaflex II is an aluminum bodied twin-lens-reflex 620 film camera, and although this Duaflex Viewfinder Hoodversion features an adjustable focus lens it has no rangefinder system, which means you have to guess the distance of the subject you want to capture.
