An interesting comment that he made caught my attention:
The Zeiss Z-series offers powerful imaging and control features to the DSLR filmmaker. Subjects are rendered faithfully, with clean natural color and quality contrast. This is important-especially on the back end of production. Pumping up or pulling down colors with Magic Bullet Looks or Final Cut Studio requires a neutral starting point. I love Canon's 50mm f/1.2L. With its warmth, sharpness, and zippy AF, it's probably my favorite "photography" lens of all-time. But when I'm shooting video, I prefer the Zeiss 50mm f/1.4 T*. Footage shot with the lens is extremely neutral and much easier to color grade. These characteristics are consistent with the entire Z-series line.
Okay, I get that neutral is the ideal (if you're going to post process) but I would have thought that applied to still photography too (assuming you're post processing in Photoshop or something like that.)
On the other hand, I'm sure that if I was primarily doing still photography, I'd want auto-focus...
