Kjell, you are the 2nd. or 3rd. person recently to say that Pentax was still making the TC's, but no place that has them listed actually has stock to sell..
Which is too bad as an adequate supply of these TC's would eleviate a lot of Pentaxians needs for larger glass..
Even Pentax Sweden have them listed and point out a recommended retail price... (you cannot buy directly from them). But when I ordered an AF adapter from Scandinavian Photo it was backordered, delivery time unspecified. I cancelled the order since I found a used one.
