I'm looking for a portraiture lens for my Hassy 500C and I might have the opportunity
of acquiring a 120mm Makro-Planar CF T*. I'm failrly new to medium format and I'd like
to know if I that lens is compatible with my 500C, a rather old model, CR34454

Is this a good lens for portraiture, head and shoulders?
Oh, one more thing: what is the meaning of the 'T*'?
