I know young people have a love for AF-S focusing, but c'mon...a 10.5mm lens can be zone focused, which is also called scale focusing....you know...estimate the distance,and set the focus distance. With the critical focusing needs of the 10.5mm lens, you ned to be precise, and get the distance estimated criticially, like within 15 to 20 feet.
A fisheye lens needs AF-S focusing? That made me laugh. Hyperfocal distance is 2.3 feet at f/8, so as long as it is set to 2.3 feet or farther, everything will be in acceptable focus from 1.15 feet to the Moon.
