Always thought autofocus was fine for planets, but Jupiter came out as a blob and I had to eat my words.

Your Jupiter blob totally changed my mind about using autofocus for planets.

Autofocus systems are tuned for things with edges, like buildings or people. Jupiter's a gas giant with no hard surface, so the camera gets confused. I had a similar issue with Saturn where it focused on the rings but missed the planet. Venus is just a shiny blob that makes autofocus give up. For planets, you're better off switching to manual and using the screen zoom to nail it.

Wait, the camera focused on Saturn's rings but not the planet? That's seriously messed up. Autofocus must be way dumber than I thought. How does it even miss the giant ball in the middle?

Oh man, I read an article about this exact thing. It said autofocus hunts for contrast edges, and a bright planet against black space has almost none. So it locks onto the rings because they have more detail. Makes sense but still annoying.
