I'm sure this has been discussed before but users have complained about the autofocusing of the Ultra. After the latest update the autofocusing is as good as it's going to get. And it's fantastic. I think people are sometimes confusing focus, with depth of field.The ultra has a massive sensor which creates a very shallow DOF. It's the reason I love this camera. Creates separation from subject and the low light capabilities are remarkable. Getting closer and closer to full frame camera capabilities in some aspects.
