Of course the *'s and limiteds are great, but you expect them to be great. These are the ones that are better than most people maybe realize.

K15/3.5*
K18/3.5*
K28/3.5
K35/3.5
K50/1.4
K85/1.8*
K135/2.5
K200/2.5*
* These lenses are rare and priced as if they are the best lenses ever made. The others are attainable price-wise. The K28 could be the sharpest Pentax 28; the 35 is renowned for color rendition and bokeh; the 50 is a Pentax 50 - 'nuff said; the 135 is just a great, fast medium telephoto.
