I like the little Nokton. I had the pleasure of shooting one for a few days (thanks Darren!) and I really enjoyed the lens. I couldn't seem to get the focus really sharp at f/1.4, but everywhere else the lens was great!
Here's a few samples:
First shot @ f/1.4 (I think I took this around 6:30 AM!)
2nd shot @ f/1.4 as well
Both shots on Portra 160, shot at ASA 100
