The HC 50mm delivers a field of you of 39mm (compared to the 35mm System). In portrait photography this is close to the barrier of getting odd, yet still fine. I use this lense mainly for environmental portraits. It also comes handy if I have to work in small spaces and need to be closer to the model.
The lense is visibly sharper then it's previous version. The HC50mm II can be used open at f3.5 and it will be perfectly sharp and contrasty already - given you are able to nail the focus.
Focusing works fast and accurate though with the Truefocus system from Hasselblad. You have to be a bit more carefull with recomposing at large apertures in comparison with longer lenses, as the way is longer and you can make more mistakes.
As most medium format lenses, the lense is quite big and heavy for a prime. It balances well on the Hasselblad body though. Compared to the Zoom's it's still a light weight.
Highly recommended lense.
