Pentax do not currently make any converters.
There was an SDM version on the Pentax lens roadmap but it was then removed.
The Pentax 1.7 converter appears secondhand from time to time and theoretically new ones are available, apparently assembled from spares.
Pentax converters have a very good reputation.

I had a Pentax 645 converter which was pretty impressive, my experience with other ones has not been a happy one, none IMO give acceptable results, particularly with zoom lenses. Other people may, however, find the results perfectly acceptable.

The Sigmas are only compatible with their non HSM range of fast lenses and although work very well (I use them with the 70mm macro, 70-200mm f2.8 and 100-300mm f4) because Pentax AF is pretty slow to start with once you fit the teleconverter you can more or less forget fast action shots.
The Pentax 1.7x is very good but again the AF is mostly pedestrian at best.

A word of warning re-Sigma converters
They do not convey the extended focal length to the camera, stick a 2x on a 300mm lens and the camera still thinks its a 300mm lens, which really stuffs up using the SR when you need it the most.

Does anyone have a Pentax 1.7x they would like to part with? Sounds like they are my best option. Many thanks for your comments.

I am looking at buying a fast zoom Pentax or Sigma and pairing it with a Teleconverter when I need more focal length, I want to use it for a action shots mainly. Any ideas or advice anyone.
Many Thanks
