Nice to have the versatility at the narrow end, it's there when you need it, and worth the extra weight.

The focus ring is mounted near the front element of the lens, a thin (1/4'' wide) ring composed of the same rubber, with deep ribs.version is fairly high in the corners (~10/100ths of a percent of frame height) at every aperture setting. It takes about 25 degrees of turning to run through the range of focal lengths, and zooming in results in a quarter-inch of lens extension.
