Teleconverter comparison

Hi, disregarding the AF feature of the Pentax has anyone out there done a comparison between a Pentax 1.7x adapter AF and a Tamron 1.4 140F in regards to image quality using different apertures?
I would be very interested in the findings and what lens was used for the test.

Thanks, Tony.
