You always hear how bad teleconverters are, but like the work Sayer does with one.. I don't see a thing wrong with this shot. And most times I think prints look even better than web. Guess I'll find out soon myself, the Kenko 300 Pro is the one I've been looking at for awhile now. Guess it's finaly about time to do it. Half the quality of this, and I'd be tickled! And even more surprising to me is it's taken at f/4, I'd have thought it would have been stopped down to f/8 or so. Excellent example of knowing your equipment, and how to use it. And I'd think going to the trouble of taking a tripod along. Good shot.
