This is a listing of every Keystone movie camera of which I am aware. I am not going to list one-ofs, specialty, or minor variants.
Some notes on the table data below:
Model links to a web page where I have the camera itself.
Circa is the year where it first appears in advertising.
Lens Type: Fixed means it has one lens permanently mounted. Turret means that there is a rotating mount with (usually) three lenses. Note that many turret cameras were sold with only one; additional lenses were extra. Zoom means the lens had a variable focal range and was manually adjusted. Power Zoom is a zoom controlled by an electric motor.
Lens: Focal lengths are given where known, but typically only max apertures were quoted in advertising specs. "C-mount" means that the lens is compatible with the c-mount interchangable format. I'm not well-versed in this: it may be that all (or nearly so) of the fixed-mount cameras are C-mount compatible.
Exposure: Auto means the camera has an auto-exposure mode. Manual means the aperture must be set by the operator.
Focus: Fixed means the lens has "universal" focus and cannot be changed; it's also the least expensive. Variable means that the lens must be focused by the operator. Note that on turret cameras, it is common to have one variable-focus lens (usually the tele) and the others are fixed.
Finder: Frame means there's a folding metal frame finder, which was very common on 1930s-era cameras because it was inexpensive and also reduced the size and weight of the camera. View is some-sort of enclosed box with a lens. Reflex means that the view comes directly through the taking lens via a split-image mirror. This is the most complex and expensive option.
Docs: links to operator's/owner's manual. I have only included links where the models match up properly.
Src: this is where I got the information. These are listed at the bottom of the page.
