Yes: “The 150mm f/4.0 is a unique, special application lens offering variable soft focus and use as a normal application telephoto at smaller apertures” ©
A special type of spherical aberration has been purposely introduced into this lens to
produce photographic images that are sharp yet which have an alluring softness.
And the highly advanced design using 3 new types of optical glass has made
possible extremely precise correction of all other types of aberrations as in standard
lenses as well as superb color balance.
The soft focus effect is eliminated when this lens is stopped down to f/8 or more so
the same sharp images obtained with standard lenses are available when desired.
And the soft focus effect can be varied at will by using the three different Softness
Control Discs provided with the lens. ©
https://ianbfoto.com/downloads/Mamiya%20RB67/Mamiya%20RB67%20150mm%20Soft%20Focus.pdf
I use it with the Fotodiox Mamiya RZ/RB67 lens adapter:

which is very convenient.
I dream to modify it additionally, by replacing the back part of it, to make it able to be used upon the Phase One 645DF+, but I am not certain in the success yet.

Today I disassembled the back of Fotodiox Mamiya RZ/RB67 lens adapter, only to discover that it is quite impossible to use it with 645 system, due to the problems with infinity. I had been very well disappointed.

Well, the lens is really modern incarnation of the “Aplanat” with the very sophisticated changeable diaphragms. So, it might be called – “the very well developed Meniscus “ to the certain way.

Yes, I will completely agree with you. Especially for the women’s portraiture. But not only for that.
