The proper name is Ciné-Kodak Magazine 16, but I've been putting Kodak first to group them logically.
This one takes interchangable bayonet-mount lenses: a 15mm ƒ/2.7, a 25mm ƒ/1.4, a 25mm 24mm ƒ/1.9 (standard), a 50mm ƒ/1.6, a 50mm ƒ/3.5, a 63mm ƒ/2.7, a 102mm ƒ/2.7, and a 152mm ƒ/4.5. I have the 50mm ƒ/1.9 and the 15mm ƒ/2.7, which I believe were the standard kit lenses. The instructions say that you need a Ciné Adapter Type M to make the other lenses fit the mount.
I have the original instruction manual for this camera on my manuals page.
