For images shot with EF 815mm f/4L USM Fisheye, a fine-tune
slider is also displayed when you select [Emphasize Linearity]
from the [Effect] list box.
Adjust the amount of correction for distortion aberration with the
adjustment slider, and then adjust with the fine-tune slider if more
adjustment is required.
When the list box for selecting an extender is displayed, select
the extender attached at the time of shooting from the list box.

Effects of Distortion Aberration Correction for
Fisheye Lenses
Shot settings
By selecting this option, only distortion aberration correction for
correcting optical distortion is performed.
Emphasize Linearity
This converts the image to a “central projection” style image. This
projection method is used with general lenses.
Differing from fisheye lenses, central projection displays straight lines
as straight lines.
By selecting this option, a wide-view panoramic image can be
obtained. However, the periphery is stretched, resulting in decreased
resolution.
