The '''Folding Cartridge Premo''' cameras are a series of folding-bed cameras for various types of roll film, made by [[Eastman Kodak]] from about 1916 until the mid-20s (see also the [[Kodak Cartridge Premo|Cartridge Premo]] '''''box''''' cameras of about the same time). They might be seen as an extension of the [[Film Premo]] [[Film Pack|film pack]] cameras (''cartridge'' refers to roll film). 

There are a number of variations on the basic format. The camera has a sheet metal shell containing the winding key and a red window, into which latches the removable unit containing the bellows and the folding bed. The bed is held shut by a lever that doubles as a foot for standing the camera upright in portrait position. The front standard slides out on rails to a catch between 25 meters and 30 meters on focusing scale, which is roughly hyperfocal distance for smaller apertures on this camera. The catch can be released by pressing a latch on the front standard, allowing the camera to be focused nearer or farther than this distance. The cameras have a pivoted [[brilliant finder]], which has a cross-shaped frame that shows both landscape and portrait views. The dimensions of the camera vary based on the format of film.

The cameras have one of two fairly basic lenses: the [[achromatic lens|meniscus achromat]] two-element lens mounted behind the shutter (which has its blades exposed to the outside air,) or the faster and sharper [[Rapid Rectilinear]] four-element lens mounted around the shutter.

The camera has a basic version of the Kodak [[Ball Bearing Shutter]], an everset, five-blade leaf shutter giving speeds 1/25 and 1/50 second, plus 'B' and 'T'. 

Different models of this camera vary in details: apertures are marked in Kodak's own simplified system (numbered 1 - 4) in the example pictured near right, but are marked in [[F-stop#Universal System stop numbers|Universal System]] stops (stops 4-64, equivalent to f/8-f/32) in the example shown far right. 

McKeown lists several sizes, each taking a different type of film:<ref>{{McKeown12}} p515.</ref>
* '''No. 2''' (2¼×3¼ inch  (6x9cm) on [[120 film]]) (This is the only format of film that is still available for this camera.)
* '''No. 2A''' (2½×4¼ inch on [[116 film]])
* '''No. 2C''' (2⅞×4⅞ inch on [[Film sizes and designations|130 film]])
* '''No. 3A''' (3¼×5½ inch on [[Film sizes and designations|122 film]])
