I don't own both, but I have used them. Very, very few lenses can touch the 135/1.8 for sharpness and separation. The rendering is very special and the bokeh is wonderful to me. The STF, on the other hand, is all about that bokeh. Terrible light gathering, (T/4.5) and very good sharpness. Doesn't distinguish itself from the Canon or Nikon 135's, and is a bit pedestrian. Until you use the Smooth Tranistion filter well. There just is nothing that touches the bokeh. I like the Fuji 56/1.2 R APD alot, but I love the STF.
The STF excells in floral pictures for that dreamy separation, and for portraits with backgrounds that blur. The STF defines good bokeh for me. So while others like more "active" bokeh, the STF's smoothness creates what many on Dyxum call STF Lust. I have it bad.
