<p>Wouter, Hector, and Jochen thanks a bunch for your thoughtful advice, I appreciate it. I think I might skip the Nikon 85/1.8D despite its good price and go straight for the Pentax or Sigma 85/1.4, they are rated almost identically by <a href="http://www.pentaxforums.com/reviews/sigma-85mm-f14-hsm/review.html?src=lrdb">this review</a> and users tend to rave about their bokeh, which appears to be on par or even smoother than with the Nikkor 85/1.4D. My K-3 focuses most of my lenses quickly and accurately, so I can't wait to see how it does with the 85/1.4 :)<br /><br /></p>
