3d - 35 mm adaptor or not?
 

what do you guys think? is it necessary a 35 adaptor for 3d or not?

one of the enhancements adapters give is the 3d feel in the image but shoting real 3d with two cameras that effect is not that needed, because the 3d is done with the other camera, what do you think about this?

the focusing could be done by adjusting the inter-camera rotation so you adjust the distance of focus in the part of the image where the two shots are lined up (this would also be the distance that )

whith an adaptor there would be another issue: the inter-rotation between cameras whould match the focusing distance of the two lenses, or you would get out-of-focused images in the "screen distance" (i don't know maybe that can be used in som cinematic purpose?)

what are your ideas in those issues?
