2x EF II Teleconverter

This is my favorite 2x TC among all my TCs (the other two are the Sigma non-DG 2x and standard Tamron 2x) because it\'s the sharpest when used with my 500 f4 IS and Sigmonster.

Here\'s a couple of moonshots with this TC coupled with:

And some bird photos with the Sigmonster, 1600 mm:

On a sharp base lens, this TC can produce very decent results.
