A photographer needs an affordable, fast-aperture fisheye lens for low-light event photography, but existing options are either too expensive or lack autofocus.

The desired expensive lens has a slow aperture (f/4) unsuitable for low light, and cheaper alternatives require manual focus, which is inconvenient in fast-paced event settings.
