As a test of my new K-3iii, I took this shot of the pinnacle of Mount Wellington, from a distance of 11.4km, with my F*300/4.5.
The photo was cleaned up for colour in CS5, and a little sharpening was added in Topaz AI (less than the recommended amount, which produced artefacts) plus some micro-contrast adjustment in Topaz Studio.
If you link through to look at the Flickr image and zoom in (I recommend using a web browser, as the Flickr app tends to blur detail) you can quite clearly see the structure of the tower on the right and the tops of the basalt columns.
