DOF Calculator < OSD parameters < Main Menu
! ! !
The Depth Of Field Calculator displays 5 distances in meters…
SD – Distance to the subject (Near Limit + DOF*0.33). Also called the Focal Plane.
NL – Near Limit. The distance where acceptable sharpness begins.
FL – Far Limit. The distance where acceptable sharpness ends.
DOF – the Distance between the Near Limit and the Far Limit.
HYP - Hyperfocal distance. Depending on the aperture and zoom settings, the hyperfocal
distance reflects the optimal distance for an object to be photographed, i.e. the sharpness of
that object will be the sharpest at this specific distance.
Show DOF calculator [Don't, Separat, In Misc]
Donʼt – Disables display of the DOF calculator
Separate – Displays the DOF values apart from the Misc values.
In Misc – Displays the DOF values with the Misc values.
