The 35/2 I have is one of the best lenses I've ever owned. Better than the Pentax limiteds I had (which if you don't know about the FA Limiteds, they are up there with Zeiss and Leica in their rendering) and better than some of the Zeiss lenses I had when I shot sony (only the 55/1.8 being better).
A lens isn't the only thing that gives a picture character or soul, the photographer has to know what they are doing as well. I for one find the rendering of the f2 primes very pleasing. Sharp, but great character, especially in the bokeh.
