Just to add a quick thought to Paul's solid advice, the Pentax A2L is considerably better glass, but the price goes UP accordingly. This converter, however, is made to be used with Pentax "*" lenses with recessed rear lens element. You've doubtless considered it, but the lesser powered converters (1.7, 1.4) tend to produce somewhat better IQ at the obvious loss of power.
