Lenses made for larger formats tend to be slower to begin with. A technique I have tried is to use a lens intended for medium format shooting or enlarging with extension on a 35mm camera. A 60mm f/4 enlarging lens needs only two stops to make it to f/8. A 55mm f/2.8 macro lens needs three stops to make it to f/8. If I need to use any front standard bellows movement the 60/4 [Bogen Wide Angle] gives me a little extra coverage because it was made for enlarging 60X60 rather than 24X36. I prefer enlarging lenses for this purpose. A lens with a helical mount or maybe even a built in shutter will involve hanging a lot of weight at the front end of the bellows. Another lens I have used this way is a 150/5.6 Rodagon.
the op is looking for a lens to use on a motion picture camera, which doesn't have bellows.
