Today I had need to use it again on this great hornbill at Reid Park Zoo. To recap, the only way I could blur the fence was to have the lens zoomed all the way out. But the only way to get the whole bird in the photo was to zoom out, which would show the fence. The solution was a series of three shots zoomed in (200mm at f/2.8) and then let Photoshop Elements panorama builder stitch them together.
