People keep asking this question over and over.
As far as I know, Zeiss never made any of the special lenses required by RX Bolexes to compensate for the prism.
Switars are lenses of great optical reknown. The RX Switars were designed for your camera.

Maybe I would see a difference if the footage were blown up on a big screen?

Could this macro effect be caused by the fact that it isn't an RX lens?
Yes, it's further from the film plane than it was designed to be.
It could possibly be adjusted to have the proper rear focal distance but this would not correct for the aberrations the prism would introduce.
You'd have to weigh that against the performance of the lens in general.
Stopped down it might look OK.
(If you can only focus a few inches from the camera it's clearly NOT "within the boundaries that allow it to work" !)
