[HUG ] Re: SWC or 40mm?

Early Super Wides used different kinds of glass for various elements .
Later SWC used glass from the same pot. These cameras are optically not
identical.
Not very important for users as most Supreme Wide Angles and Super Wides
are now resting in the hands of collectors.
From SWA till 905 SWC covers over 50 years in Hasselblad history.
An exceptional case of a strong camera concept that survived all these
years.
