Pentax X70 - zoom or no zoom, here's the picture

First with no zoom, looking down the river, for a person sitting on the rocks along the bank on the right-hand side of the river, near where it disappears around the bend. You don't see anything there, do you?

Now, with full 24X optical zoom, you can see the person sitting on the bank, just beyond that biggest rock along the shoreline. (Click inside the image to enlarge it.)
My friend in the U.K. has some comments about this on his own blog, here.
