Thank you! I have the standard Sigma 1.4x and it does fit, but I want to sell it and get a better one. Funny thing is, I just tried the Sigma 2x and it *does* fit! I must have been fumbling too much when I tried to attach it in the field the other day. BTW: The photo I took using the Pentax 1.7x that day came out quite nice. I just added it to my fall photo collection last night, along with 3 other new shots: http://www.robertstech.com/fall_2k1.htm -- Mark Roberts www.robertstech.com - This message is from the Pentax-Discuss Mail List.
