I have a drawer full of converters including both current Sigma EX ones, a couple of older 1.4x ones, several rebadged Kenkos, a couple of Tamron ones and the Pentax 1.7x AF. I put the Sigma EX at the top for performance, then the Pentax and the older Sigma ones which are close and the Kenko near the bottom, but slightly ahead of the Tamron ones (none are the latest Kenko design).

The other AF converter I have used with this lens is the Kenko 1.5X AF (4 elements). It also works well, and the results are good, until you compare them with the photos taken with the Pentax 1.7X. The difference in the image sharpness is really noticeable, in favour of the Pentax converter. ------------------------------------------------------------------ Carlos Royo [EMAIL PROTECTED] Zaragoza (Aragon) - Spain ------------------------------------------------------------------ - This message is from the Pentax-Discuss Mail List.
