Here is another test, this hotel was about 1km (3300 ft) from me. Again 100% crop untouched picture. The f4 is decent and the f5.6 super sharp and detailed. So I'm glad to see it works well with distant subjects.

Here is a 50% crop test with the TC 14II attached at the zoom ring at 400mm (equal 550mm). Left side at f5.6 and right side at f8. Subject was at about 100 meters. Medium performance wide open. Much better at f8

Here is a 50% crop test with the TC 14II attached. Left side at f5.6 with the ring at 350mm (equal 490mm) and right side the ring 400mm (equal 550mm) at f5.6. Subject was at about 100 meters. Drastic difference when you backup the ring to 350mm wide open instead of 400mm. 400mm is still decent in a fit to screen view or with a light sharpening but no match for the other one.
