Sony’s autofocus system has a reputation for accuracy, and in most of the shooting scenarios the camera behaved as expected. It’s a great choice for shooting portraits of humans or animals, especially if you are working with studio lighting conditions. The ultra high-resolution images took a bit of getting used to. There were a number of times while shooting where it appeared that AF wasn’t quite nailing the focus on a subject’s eyes or face, but once the files were uploaded to a computer things seemed fine. When you are shooting at 10fps you should expect some duds, but with fast moving subjects, the camera seemed to have a bit of trouble grabbing onto faces and holding on.
