Originally posted by dadipentak You guys have sure convinced me that HD DA 1.4X TC + DA*300/4 is really a superb combination (in the right hands of course ;~). In fact, I get the sense that the TC was really optimized for that lens and the DA 560/5.6 The question for me is whether the DA TC would do better than the Tamron Pz-AF MC4 in combination with my FA*300/2.8. Has anyone seen any evidence bearing on that question? Of course, the easiest way to find out would be to buy the DA TC but...you know--price.
Not worth it if you don't have an SDM lens, IMO. I have the Kenko 1.5X PZ SHQ (actually 1.4X). IQ is close enough that you would only tell by pixel peeping the same scene with both TC's. AF is really no different on a screw lens.

Nice composition. Pretty birdy!
