Diana and her many sisters and brothers have enjoyed a cult following for decades. Gas stations gave them away if you filled your tank. The “F” stands for “Flash” as there are non flash models. They are called “Dianas” not surprisingly.
There are many versions of the camera. A few of them can be found on this website. They all use 120 size film and produce dreamy, unreal images due to their plastic lenses, wavy pressure plates and comical film advancement apparatus
