It's reasonably good for closeups, this cpu would be nearly covered by a quarter. The wide angle provides a dramatic perspective and some context where that's desired. The orange highlight of the streetlight beyond shows the 5-bladed aperture when stopped down. This won't tilt as much as a real 28/3.5 PC Nikkor so I couldn't get infinity focus at these close distances but maybe something a few feet away.
