Has anyone tried the 1.4x tele-extender with this lens?
Thanks! I haven't tried a TC on the 450mm yet, though I do own the Tamron AF PZ 1.4x TC … it was sluggish beyond my patience level on my DA*300, and bow to Marcus's more knowledgeable reply.
I have been waiting for either the K-New, which will hopefully have the extra pixels on the image space, or the new HD FF TC... or maybe both? I am thinking the K-New will be fun with this lens for birding, especially if the AF and speed is improved. The big question that remains is which sensor they used. The K-New will take up more room in my bag and cost more than a TC, but I'm hoping that's my first option, because well, we all like new toys, right?
