I'm thinking of getting some Zeiss Super Speeds for S16. Just used some last weekend and loved it, mine had little metal "ears" for focus pulling and were bayonet mount with a PL adapter attached to the back somehow. Just wondering if there are differences between the MK1's and whatever the latest version of them was? I know the Zeiss Super Speeds for 35mm had triangle blades in the MK1's and then the MK2 and 3 are pretty much identical except for the markings and maybe how you pull focus but the look of the MK2 and 3 was identical (or so I have been told..)

anyone care to shed any light on the Zeiss S16 Speeds for me?
