SL66 mount 50/4 Distagon

Has anyone had the opportunity to compare the 50/4 Distagon for Rollei SL66 mount to the Hassy mount lenses?

Is it safe to say this lens is closer in pedigree to the older Hassy C lens than the CF/FLE? I just picked one up on ebay: Rollei HFT, the all black later style.

Either way, I'm sure I won't be disappointed. It will be nice to finally have some wide angle capability in medium format.

No response here but I got one from Kornelius at Zeiss. For posterity:

The Distagon 4/50 for SL 66 is the old type from the Hasselblad C era. By
today's standards I consider it very good in the center, not impressive in
the corners. But as far as I know there was no more recent type of Distagon
50 for the SL 66.
