The Popular 12 has an unusual body, with film spools fitted top and bottom and the film running vertically. It is similar to the Dynamic 12, but with sliding back catches (rather than poppers), a plastic (rather than cord) carry strap, and a viewfinder cover/shade. Viewfinder optics are plastic. The back is decorated with a fluted pattern, and has a central red window with a rotating cover. The shutter release, mounted under the lens to the user's right, is pushed upwards to operate. The lens is a simple meniscus-type, behind the shutter, fixed-focus and fixed aperture, labelled "Coronac". The shutter is single-speed, and oddly there is an I/T marking above the lens, but no control to set T mode. According to McKeown, there is an improved model with an I/T synchronised shutter.
