The refocusable range varies widely, depending on the zoom and focus positions of the camera when a picture is captured.
The refocusable range with the lens zoomed to a 100mm focal length (35mm equivalent) and
the optical focus at approximately 42cm. Note the relative size of the refocusable range.
Effective use of the refocusable range and the depth composition features on the Lytro ILLUM is the key to creating
extraordinary Living Pictures. To find out how to best leverage these tools, visit training.Lytro.com for in depth education
