By looking at data available at Photons to Photos (link), the focal length reduction of the Z 105 MC is rather pronounced from infinity (magnification = 0) to shorter distances. I have collected the data for both the Z 105 MC and the AF-S 105 VR and plotted them in the figure below. As you can see, focus breathing of the Z 105 MC is really huge, even at "normal" focusing distances.
The "old" AF-S 105 Micro VR doesn't change significantly its focal length from infinity (FL = 104 mm) to 1:4 (FL = 102 mm).
On the basis of these

Focus breathing, shifts in FL and changes in aperture are a royal PITA when doing serious macro work.

Someone asked about comparing this lens to the 100/2MP. There's a review that comments about it and the 105 VR here:

relevant excerpt:

Enter the Zeiss ZF.2 2/100 Makro-Planar T* (hereafter the 100MP). It’s a full stop faster than the Nikon at f2, which it impressively maintains throughout the focus range; it also doesn’t shorten the focal length as it focuses closer, which maintains working distance, as well as minimizes focus breathing (especially important for videographers). The downside, of course, is that a huge amount of extension is required to deliver only 1:2 magnification (extension for a given magnification is proportional to the focal length). 1:1 would have been nice, but I honestly don’t know where they’d pack that extra helicoid. Near focus limit...Show more

The complaint about the amount of extension required by the Zeiss is no joke. The amount of extension and focus throw is huge.

The 105mm Z has some focus breathing. But it is less than the reduction in focal length may suggest, because the position of the entrance pupil is moving with changes in focus distance. For best results, especially with stacking, do not adjust the focus distance, but move the camera.

So I found a good deal on used one and couldn't resist. Haven't shot macro in years but this is a seriously impressive lens. I really like how it handles as well. Here's a quick snap in the back yard with the Zf hand held. ISO 100 and f./3.3.
