is there a lens multiplier?

when using one of these adapters do the 35mm lenses work at the 35mm field of view or at multiplier of that number?

Hi Stephen.
No there's no multiplier when using 35mm Cine lenses. That's the advantage of a 35mm adapter as opposed to a normal mechanical mount adapter like the Canon EOS. A 35mm adapter will keep the same field of view and DOF characteristics of the 35mm cine lenses you use.

you're thinking in relation to a 35mm STILL camera's frame. It may be about 1.5 - 1.6x the magnification compared to a STILL camera full-frame 35mm. But motion picture film runs vertically (in most instances), so you're dealing with a smaller frame than still photography 35mm film which runs horizontally. A standard 35mm still frame is 24mm high by 36mm wide. A 4-perf full aperture 35mm frame is 18.7mm high by 24.9mm wide. The still frame is a fair amount larger than the motion frame, therefore for any given focal length, the field of view will be wider.

However, you probably won't ever hear someone complain that the DOF of a mini35 is too deep in relation to a still camera. The mini and pro 35 do the same thing with the same resulting "frame." They are simply intended for different cameras. Both approximate the field of view and depth of field of 35mm motion picture film, not still film.
