The description in the link says:
They feature a renowned Zeiss-licensed, Rollei-built 80mm f/2.8 Planar lens and incorporate center-weighted TTL lightmetering with a viewfinder read-out and the capability of TTL "Off-the-Film" flash exposure.
This "Zeiss-licensed, Rollei-built" stinks a bit of marketing lie to me. Isn't it much more likely that the lens are very well built by Zeiss themselves? That wouldn't detract at all from the qualities of the camera in any case.
