Hey, I've run into this exact issue with my own setup during night shoots. First off, try bumping up your ISO a bit to let more light in, which can help the autofocus system grab onto details better. But watch out, too high and you'll get noise in your shots. Also, switch to continuous autofocus mode if you're dealing with moving subjects; it tracks them as they shift. Another trick is using the camera's live view on the screen instead of the viewfinder. It often focuses more accurately in dim conditions because it uses contrast detection. Works great for starry skies. And for stability, a sturdy tripod is key to avoid blur from shaky hands, especially with longer exposures. Give those a shot and see if it clears things up.

hunch about air moving clothes is probably right but sometimes the hangers only twitch a millimeter and that is enough. I actually had to immobilize the row of shirts. Two zip ties around the rod with a small gap creates a corral so the hangers cannot slide and sway. can also clip a couple of hangers together near the hook to dampen motion. Then point the sensor down the wall rather than across the rod. I left a tiny sliver of black tape on the outer edge of the lens to keep it from seeing the door gap. Works great.
