Stay at home

The downside for me is my penchant for dragonflies, and the minimum focal distance of the lens is 6m, nearly 20ft. However, I can still get decent images. I'll post one of a 4-Spotted Chaser here to show a characteristic of the lens: some terrible bokeh for out-of-focus specular highlights that diffractive optics can give with a series of concentric rings. I have never seen this with my 400mm DO II or Nikon 500mm f/5.6 PF. Canon has cut corners in its design here.
