After testing my Nikkor 85mm f/1.4 through Boujou 3 and getting a lens solve of around 50mm, I decided to test an actual 50mm lens.
I mounted a Nikkor 50mm f/1.8 lens on my Nikon D200 and moved it forward step by step toward a white board on which I had marked a few tracking crosshairs in erasable ink.

Boujou 3 appeared to perform well, reporting a point cloud revealing a push-in across a flat, vertical wall-like surface.
Maya 7 reported a camera focal length of a bit under the 50mm lens I had in fact used. Normally I'd be pleased at such a seemingly accurate answer, but I'm not quite sure how to interpret this data.
The problem is my Nikkor 85mm f/1.4 also solved out at around 50mm.
Further testing with other lenses is warranted.
