Photographing birds with an 18mm ...

I had found a place where more than thirty hoopoes were fed, so I thought about doing something different, taking advantage of the wireless triggers and the second body I barely use ... They have taken the area well, I make the preparations just two hours before dawn, on the one hand I have to place the body with 18mm and on the other hand I have to place myself in the hide, and so take the opportunity to shoot a photo ... it seems that they are arriving, they begin to feed and one of them is planted decided in front of the camera with the 18mm ...
