Prolly a "I should know better" question, but when shooting through the fence, did you have to remove the hood?
A big NO to that question as the hood protects the lens from the fence. I actually place the hood right against the fence so as to get it just the right spot to avoid any interference from the links, which is minimal anyway because of the focal length. The only time I seem to notice an issue is when there is harsh sun reflecting on the links I am shooting through, otherwise I have good success doing this. Of course I'd much rather be on the other side of the fence but in the spot I was shooting these images from, there was maybe 10 feet if that between the foul line and fence so it was not possible.
