I have both Nikkor-Q 135/2.8 and 135/3.5. Then I have the 135/2.8 K-version I think it is called. It is a bit shorter than the Nikkor-Q 135/2.8.
When I tried a Nikkor-Q 200/4 on a digital body (DX) I got surprised how good it was.
In the film-days I was told not to get the lens as it was not able to produce a sharp image at all. It was probably bad technique (lack of focus, camera shake) that caused this.
It produces nice bokeh.
