Alek, At the PDMLUK event last summer, I took most of the airplane pictures with a A*400/2.8 and the AF1.7TC, on a Z1. See http://oksne.net/ for the images, and Cotty's page for pics of the combo http://www.macads.co.uk/pdml/index.html.
After also using it with many other lenses, I have found that AF with the TC is very accurate with f/2.8 (or better) lenses. Precision with eg. M-200/4 is ok, but no more than that. Lenses of apertures darker than f/4.5 will make the AF hunt in low light. AF is quite fast. Comparable to eg. FA50/1.4. It works with all bayonet mount pentaxes. Even with 67 or 645 lenses and the suitable converter, if you focus with the lens wide open. :-) Wide open, the converter produce softish images. A 50mm and the 1.7TC makes a very nice portrait combo, with a convenient soft-effect. Stopped down a bit, it's quite good optically.
