The focus function button on the lens barrel can activate full manual focus or auto focus. There is also a digital zoom function that can be triggered by the two magnification buttons built into the camera body. Additionally, the auto focus function on this camera is one of the best I have seen -- it is center-weighted, meaning that the camera looks to the center of the frame to determine focus.
The XF305 also boasts some pretty impressive stats: its highest recording resolution is 1920x1080 at 50Mbps, and footage is captured in MPEG-2 codec in LongGOP format with 4:2:2 color sampling. HD-SDI, SD-SDI and composite outputs are available as well. Watch my video to learn more about this versatile new camera.
