Not a terribly interesting bird...

...but I wanted to share the results of the100-400 and a Kenko1.4x Pro 300 TC. This mourning dove was shot wide open at 1/800 with ISO 400, 560mm equivalent. The posted pic is about a 25% crop. I picked this TC up because of comments on POTN, and the very low price, and it is certainly worth it. I hope to get out and use it on more worthy subjects soon.

Its a nice shot.

very crisp, i can see you are going to be very happy with your tc.

Very very crisp - enjoy the tc.

with the 1.4 you have managed excellent good focus on the dove, it's clear and crisp and nice colour, well done.
