Tell me how do I Back Focus a camera fitted with a ZOOM Lens?


This can be achieved by following these steps.

☛ Set the lens to full wide angle view.
☛ Set the physical focus of the lens to infinity (clockwise viewed from the front).
☛ Aim the camera at an object at least 30 Meters away.
☛ Release the camera back focus mechanism.
☛ Adjust the back focus to obtain optimum clarity.
☛ Zoom the lens in to full telephoto and focus on a nearby object.
☛ Keep this object in view as you slowly zoom out and if all is set correctly it should remain in focus (track).
☛ Secure the back focus mechanism.
