No, actually I was asking about the SK technical camera lenses. I've been looking at mid-long lens options for my Alpa and the SK 120/5.6 comes in two varieties so hence the curious question. It might be somewhat academic for me though as I've pretty much convinced myself that I want to go a little longer I think.
Btw, the new Phase One 120 TS does look interesting, especially as the Hartblei heritage isn't involved this time. I only hear good things about the Schneider glass on the Mamiya platform.
