The Hasselblad 110mm f2 is not the sharpest lens around, but that is not what makes it such a nice lens.
It's more about how it looks wide open.
While it is not that sharp the bokeh and shallow depth of field give what is in focus more apparent or perceived sharpness.
The contrast of detail in the in focus areas with the softness of the out of focus areas is what does this.
It does have fairly pronounced Longitudinal Chromatic Aberrations (also called Bokeh fringing), but this is common with most very wide aperture lenses.
This is actually one of the things that gives the images a sense of depth.
Sometimes a lenses "technical defects" ad up in an interesting manner producing a quite a characteristic look.
Another issue is finding a nice copy as this is now an old lens. I have seen quite a few with some haze from the thread grease that over heated in a car or something.
Taking it apart and cleaning it will improve sharpness and contrast. Also how the front and rear elements have been cleaned makes quite a difference.
When picking up one of these you need to check for clarity. To do so put a small point source light pointing at the lens on a dark background and look through the lens.
Sometimes a lens that looks clean in even light will show problems this way.
It took me a while to find a nice one and I like the results from it.
Hasselblad 110mm f2
It one of the nicest bokeh lenses in MF. The Contax/Rollei 80mm f2 being another, but IMHO the "grand master" is the Fuji gx680 180mm 3.2
