Bob,with respect, I would say setting your camera at f16 /32,000 Iso with a f1.4 lens for low light interior ..is totally wrong.. you would rarely want to shoot f16 in the blazing sun let alone a dark garage .. cranking up the ISO to this limit on a f1.4 lens to shoot f16 in low light is absolutely the wrong way round..
Brandon.. I see you did this to have maximum depth of field due to previous focus problems.. f1.4 even on 24mm it will be shallow.. you could go up to f4/5.6 but you dont need f16.. and ISO 32,000 way off the scale.. you would only use this as some extreme emergency setting like a dark colored UFU landing in the night ... the A7III has very good AF.. check your settings.. are you in movie mode?.. Auto focus continuous is what you want.. WIDE focus area.. with Face detect .. for when you turn the camera to yourself..
