Don't use auto focus. If you are shooting a scene with a known depth of field. Disable AF and use a fixed aperture sufficiently small to make the entire scene within the selected DOF. You might need to use lights if you need a small aperture.


Yep, autofocus on video is a pain. Better to just focus once, then switch to manual and leave it there. Especially if you're doing review videos, the camera won't need AF anyway.

Okay, just tried that and it didn't work. I can't bring the product up close or far away without it being blurry.

I'm shooting at 3200 ISO and f.25.
