Yeah, I figured that would be the case. I do have the Kiron MC7 and Tokina Doubler TC's in K-mount (and I think a Vivitar macro-focusing TC, also) on hand I could try as general purpose TC's; my Tamron 1.4x SP and 5-element 2x TC's are for Nikon.

Of course, that's overlooking the disasters that add to one's net costs dealing through a certain auction site, with its X#℅@¥*π, so-called "buyer protection". Mom didn't know about internet auctions.
