Took the 85 for a spin out a Reader Rock gardens here in Calgary. Most of the blooms are gone, but some nice fall colors accent what was left. I'm getting the hang of the fast, short tele vibe, but its not a natural thing for me just yet. My personal keep rate is improving though, so my praise for the lens can grow a little more too.
If I was able to redesign this lens (by magic of course) I'd have it focus more closely, even just to the 1:5.8 or so of the Nokton - bokeh takes weird turns in tight. I'd still say its a little less versatile than other lenses, esp on APS-C. There were times I felt that at its minimum distance, I'd like to be able to capture more, rather than stand back and add too much depth of field. I can honestly see why Pentax hasn't rebuilt a fast 85 yet. Meanwhile, it does do some unique things. Pardon the different pictures sizes - I'm transitioning some stuff (but not all of it) over to Zenfolio at the moment.
Zeiss Planar T*85, all at 1.4 (I think, might have stopped down to 1.7 or 2 for exposure)
Id say its bokeh is a lot less sensitive to light than any other lens I've used. It tends to render highlights in a muted fashion, the overall effect seems mottled - like oil paint to me, vs the Noktons more light sensitive water-color and delicate highlights.
