Red Browed Finch (Firetail)

Looks like the light here may have been a bit bright, but your exposure is nice for this shot overall. I am wondering about the bokeh in the background-is it natural? Very odd. I like the way this interesting and pretty bird is framed in by the branches-the colors are nice, though the branches seem to have a slight blue-green color cast. This is a fine lens, it is next on my shopping list.

The bokeh is not just background blur, but foreground blur also. This can lead to unusual effects as seen here. Thanks for the kind words, and yes, it is a superb lens.
