DMF or Direct Manual Focus techniques for Sony Alpha Cameras

In this Tutorial Mark shows how he uses DMF or Direct Manual Focus Mode to achieve critical sharp focus when using wide apertures with subjects that are close to the lens. Mark also shows how he can override his current Focus settings with a single press of a custom key to use DMF in conjunction with Focus Magnifier to nail sharp focus every time.
