With respect to the original question:

From your comments, I presume that you must use the Nikon PB4 bellows unit in order to use a dedicated Nikon slide copier and that, due to interference between the camera body and the bellows unit, you must use the 27.5mm Nikon PK-13 extension tube between the body and the bellows unit.

Using the PK-13, PB4, and PS5 simultaneously forces constraints on the minimum and maximum focal length of the lens to get your wanted 1:1 magnification.

The shortest lens you can use is 71mm (due to the combined lengths of the tube and closed bellows).

With the PK-13 and PB4 mounted and the PS5 slide copier extended as far forward as possible, the longest slide-to-film (or sensor) distance possible is about 397mm.

Consequently, to get 1:1 magnification you can use a lens no longer than 99mm focal length.

So, if you must use both the PK-13 and bellows, then you must choose a lens in the range of 71mm to 99mm to get 1:1 magnification.
