I forgot to write, I also own the matched Tamron converter for the 90/2.5. Mine didn't work well: to low contrast. I suggest a cheap 200mm. Costs the same as the converter and works way better for me. Joachim - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
