With a dome port my camera needs to be on its macro function to allow focusing on the close virtual image the port creates. I get variably out of focus images otherwise. Assuming you have a dome port its possible that you are only just able to focus close enough without switching to macro mode, so could have trouble locking focus on AF.

Dome port? Macro? Normally Dome ports work with wide angle and Macro lenses work with flat ports. I'm confused, so could you explain?
