Yes - I use it with enlarger lenses (Ektar 100mm and VHE 150mm) that
happen to press-fit into a BR-2 ring, providing the Nikon bayonette.
Strong skylight filters correct the greenish color of the enlarging
lenses. Both focus to infinity and provide sharp images. I originally
put the outfit together to shoot evening lake water reflections,
for which it worked moderately well. Later I used it for landscapes.
Remember that while you can shift the angle of the plane of sharp
focus, DOF at wide apertures is not great, so if the subject does
not lie close to the selected plane there is little advantage to
using this very awkward system.

>- Has anybody heard about this 100mm f/4 short mounted lens ?

Yes, but don't bother. The Nikkor is an over-priced collector's item,
and the image quality isn't great. The Novoflex is cheaper, but worse, optically.

Other than the two above and a rare short-mount Nikkor 135mm, I don't
know of any.

>- How much is it for a used Nikon PB4 bellow ?

They are semi-collector's items, going for about $250-350 in the US.
Hope This Helps
