I am surprised nobody mentioned the K35/3.5, or if you cant find it any of the screw mount takumar versions.

Image quality is staggering, and price is low.

(bokeh could be better, if this is an issue the K35/2 is better, however few 35mm lenses have great bokeh.)

I have used both the jupiter 9 and the 85mm/1.8 (K.version). The jupiter 9 was not a top performer, but still a very good lens, but the pentax was better, so i stuck with the pentax.
