In this video I show you how to setup a custom button (C1) for quick focus magnification on the Sony A6000 Alpha (Nex) mirrorless camera and focus far more accurately than can be achieved with focus peaking alone. This is a video response to some folks having trouble getting sharp focus with the Metabones adapters and manual focus lenses.
Shot using an iPhone 5S and FiLMiC Pro attached to the Sony A6000 using a Kamerar 11" friction arm. 4x4x4 LED cube kit from www.freetronics.com is shown in the background. The flicker is only visible because of the difference in the electronic shutter on the camera.
