Paul,
It is a nice picture, but I am curious about a certain aspect of it that
might be a characteristic of the lens:
The background (especially the green from the tree right in the middle of
the photo) seems to have some type of high-frequency "jitter".
I wonder what's the origin of that?
I could see a few different possible sources:
1. strange bokeh in combination with the small features of the tree
2. camera shake (motion blur) that is compensated for the in-focus items,
but not quite for the background.
3. sharpening combined with one of the above
4. ... (?)
What do you think?

Took a break and sat outside at noon today. This guy was too distant - the
pic is only about 30% of frame - so it.s nothing special. But it's a nice
example of lens performance. K-3 DFA 150-450, f5.6, 1/1250th, ISO 1250,
handheld, 450mm. I like the way this combination locks in focus, but at this
distance, about 70 feet I'd guess, finding the critter in the tree is a
chore. But once I get a single point on him, it.ll lock right in.
