So I see:
3-mode stabiliser (like all the new Big Whites)
Focus Preset
AF/PF/MF, I'm presuming the PF means Power Focus
Focus limiter 2m-6m, 6m-inf, 2m-inf
One big ring and one thin ring, dunno which would be zoom and which focus
AF stop buttons (even if they'd be a fair distance to reach by the looks)
Filter holder like all Big Whites
and the 1.4x Teleconverter, looks like it can be locked in either of the 1x or 1.4x positions (which would be very useful, I'd be locking it all the time for transport).
This lens is definitely shaping up to be a 'Cream Machine' (but i'm talking about my pants, not the Bokeh)
