I own two film cameras an Eclair NPR and a K3 both 16mm (U16 Converts). It's a real kick shooting film and I prefer the look. But there is a difference between knowing how to use a film camera and knowing how to expose film or proper exposure regardless of what kind of camera you are using film or digital.
The most important thing I learned from shooting film is shooting with a "Full Manual Exposure Head". Watch the light, use a hand held meter, set the camera, shoot.
The beauty of any digital camera that can be set to full manual is you can practice your exposure, framing etc... skills with no film costs.
Any DSLR with a 1.5 or so crop factor will give you almost the same focal length as a normal 35mm motion picture film camera. The mistake many make is thinking a full frame 35mm DSLR such a Canon 5dmkII is the same as a normal 35mm motion picture camera it is not. The 5D is a Vistavision frame, much larger frame.
