Name;
Kodak Duaflex IV with Kodar F/15 lens.
Manufactured by;
Eastman Kodak Company, Rochester, NY, USA.
Date of manufacture;
1947-60; this model, 1955-1960.  Duaflex cameras were all the same optically during this entire run, with minor changes over the years like adding a viewfinder cover, different strap lugs,  and flash syncing etc.
Price;
originally around .50 for the camera only, and .50 for the deluxe outfit via a 1957 popular mechanics ad.
Build material;
plastic with aluminum trim; finish texture is called ‘Kodadur.’
Weight and size;
camera only, 16.5oz (470g)
Dimensions;
camera only, 2.85″ (73mm) wide, 4.70″ (117mm) tall, and 3.0″ (76mm) deep closed, excluding protrusions.
Focal length;
75mm.  The camera “sees” about the same horizontal view as a 35mm (135 format) camera “sees” with a 50mm lens.
Aperture;
f/15 Kodet lens
Focusing distance;
scale and zone focusing, about 4′ to infinity.
Original print size;
standard oversize prints 3½” x 3½,” at this size will look excellent.  Today you’ll most likely get 4″ x 4″ prints from your lab.
Approximate resolution;
will make great 5×7″ prints, or good 8×10 prints.  Properly scanned images look good on a computer screen about 2400-3000 pixels wide.  See Sample images at bottom of page.
Lens;
three elements, coated, Kodak uses the word ‘lumenized,’ everyone else uses ‘coated’ lens.  Construction is: achromatic doublet, and one focusing element in front.
Shutter and speed;
self-cocking (as you press), spring loaded rotary shutter.  Shutter speed about 1/40th second, with instant and time setting, see shutter test screen below.
Film;
12 6x6cm or 2¼”x2¼” exposures with 620 film.
Double exposure prevention;
yes, but you can push in a small lever by the shutter button to over-ride this if you want to.
Accessories for this model;
brown ‘field’ case number (possibly 62/63fc).  Kodalite flash no. 710 or others, and possibly some filters although I don’t know what size.  The ‘Kodet’ lens takes Kodak 6A filters.
Useful features;
different apertures to choose from, double exposure prevention, very bright viewfinder window and a sharp focusing lens.
