Don't discount the pre T coated C lenses, they are in my humble opinion, just as good, especially the 150 and 250, and pricing is very good. Like Leica lenses, the Zeiss for Hasselblad lenses are of a uniform high quality, just find a clean one with a good shutter. My most used is the 150mm Sonnar, very nice, and a must have after the 80mm.
