The best ?
The Pentax-FA* 200mm f4.0 macro has a reputation of being the finest lens Pentax ever produced. Unfortunately is was discontinued early last year and at this time there is no replacement model.
Current models are the Pentax-DFA 100mm f2.8 and the Pentax-DFA 50m f2.8. Bother are very good but the 100mm focal length will give you a little more distance between camera and subject if photographing skittish insects.
There are also options from Tamron and Sigma who offer a number of good macro options. I don't think theres a bad macro lens on the market and it's more a question of what focal length macro lens would suit you best.
