In the Hasselblad lens line the name "Sonnar" was prevalent
The not so non recent 180 CFI Sonnar was said to be one of their best lenes.
Or "is" maybe I cant tell what's going on over there with those guys.
A big improvement over the 150 C Sonar I started out with and still have.
Is this Sonnar in name only?
What's in a name?
