Having said that, monkey always is going to center the chain link or bars between his eyes... after all, he can't see through metal, and to see out he has to look through the holes.
As far as the focus goes, you do the best you can... it was extremely dark there, and I was pushing to get any shot at all. Shooting through the fence means putting the focus point on his eye (something tricky to do when he's moving, the light is dark and the fence is more bright than the monkey's face...) and shooting at f/3.2 means that depth of field is razor thin when shooting up close.
You do the best you can with the situation that presents. I didn't quite nail focus on it, and I could fake it in post a bit, but it is what it is.
The EXIF:
D300, 70-200 VR, f/3.2, 1/250th (he was moving), ISO 800...
OMG, to get that result when it was taken in dark lighting conditions is amazing. Its eyes are so expressive, and such an interesting colour. Nicely done! (as always. Except for that penguin shot..... )
