A friend previously told me that the 300 f4 works better with the TC than without- I laughed. But now, I am convinced

By the way, what did you do with this image? This is sharp, nicely exposed, well composed (although I agree with Abhishek about lesser space to the left) and has good looking colors. Patience pays off, you told me and it did!!

Could you try to recover something from the dark underparts? By the way, did I tell you that this is my fav image of your's?
