edit: Wanted to say James, those are classic Nokton Paintings - you're last two shots. I almost just accepted them as normal these days forgetting they were so... Nokton! heh. Makes me think a high quality glossy page book of Nokton Paintings could be a really nice thing... anyone got any publishing connections?
After I received my K20, my fiance has taken up manning the K10. Her favourite lens has been the VL90, she likes the sharp, close-focusing and small size. Seeing her type of shots, I recommended she try the Nokton for a while toward the wide end and see what happens. After about 20 minutes she comes back and says "Don't like it, can't get a sharp shot." So I look at her pictures to perhaps offer some advice and the first thing I see is this:
Nokton @ f2
It emphasized to me the Noktons unique personality. Sharp it can do, but its so strong in blur character it can overshadow its own sharpness and throws off a lot of photographic natural instinct.
The love/hate with this lens comes from either rolling with what it gives, just direct it and love what its actually doing under f2 and make the best you can with it, or stop it down to 2.8, where normal life begins. FWIW, the T*85 is a LOT like the Noktons big brother, for those that were interested in reaching out with their Nokton eye a little.
