Kodak Duaflex Camera Series (1947-1960)

The Kodak Duaflex Camera is a simple 620 film camera with a large brilliant finder in a twin lens reflex configuration. Cameras were produced by Eastman Kodak Company in Rochester, New York, from 1947 to 1960.  The shutter is a single speed rotary shutter with a "bulb" setting.  The shutter speed is about 1/25 or 1/50 second. They came with two different lenses: a fixed focus Kodet lens (75 mm f/15) and a focusing Kodar lens (72 mm f/8).  The Kodet lens is a meniscus lens with an aperture stop behind the lens.  A Kodar lens is a three element anastigmat with front cell focusing from 3.5 ft. to infinity.  The Kodar lens has a lever to select an aperture of f/16, f/11 or f/8.  The stops are round holes in a metal plate, so you can't select intermediate f-stops.

The Duaflex (1947-1950) is black plastic and aluminum.  The ones with a focusing lens have a double exposure prevention device that locks the shutter button until you advance the film.  The ones with a fixed focus lens do not have double exposure prevention.  The flasholder is a dedicated model.

The Duaflex II (1950-1954) added a flip-up hood for the viewfinder.

The Duaflex III (1954-1957) added double exposure prevention to the fixed focus model.  The flash connection was changed to a pin-and-screw Kodalite connection.

The Duaflex IV (1955-1960) changed the color scheme from black to brown and tan, and added more exposure instructions to the focusing cameras.

A Duaflex makes the same size picture as the Brownie Hawkeye (https://fourelementsinthreegroups.blogspot.com/2018/11/front-back-this-brownie-hawkeye-was.html). It is a sunny day snapshot camera, similar to the Argus Seventy-five (https://fourelementsinthreegroups.blogspot.com/2019/09/argus-seventy-five-1949-1958-and-argus.html) or the Ansco Anscoflex (https://fourelementsinthreegroups.blogspot.com/2020/06/anscoflex-1953-1956.html). It was made for slow to moderate speed black and white (Verichrome, Plus-X) or color negative (Kodacolor) film. Current 120 films respooled onto 620 spools work fine.

The Children's Memory Garden was dedicated October 18, 2022.  It contains names of children who died violently in Nashville.  I was visiting the park this January and noticed someone had left a rose.  Kodak Duaflex with Kodar lens.  Arista EDU Ultra 100 film developed in XTOL.  Cropped from the original square to a portrait orientation.
