Depth of Field
Back on the topic of the Nikkor 18 - 200, here's a shot showing depth of field at extended zoom:
F 5.6 ... 200 mm ... 1/60 sec
These are the same shot. The first image has been compressed to save bytes. The second image is a crop; if you click on it you will see it at 100% relative to the original.
This shot was taken on a windy day - I missed the moment when the leaf was fully vertical but am nonetheless impressed by the lens's auto-focus working with the moving target.
Having used the lens for a couple of months now, I really like the large aperture bokeh at extended zoom, though the narrow depth of field does require precise attention to focus, as the following shots show:
F 5.6 ... 120 mm ... 1/160 sec
This time the leaf is in focus and the brick blurs slightly. Once again an uncompressed crop to show the detail at 100%.

Despite the shorter zoom, the area of sharpest focus is at the intersection of bricks between the leaves. Ho hum... boring.
