This is the image with all the zooms in action. This image is different from the third in the first set only because I applied the sharpening in Photoshop. It was reduced to 31.25% of its original size in Photoshop.

It seems to me that this shot is actually a bit sharper than the previous one, which makes me wonder if perhaps I didn't do as good a job of allowing the camera to focus itself on that third shot.
