Keystone correction and perspective control (Keystone Comp.)
Keystone distortion due to the infl uence of lens focal length and proximity to the subject
can be corrected, or enhanced to exaggerate the effects of perspective. Keystone
compensation can be previewed in the monitor during shooting. The corrected image is
created from a smaller crop, slightly increasing the effective zoom ratio.
• This option is available in P, A, S, M, and
B
modes.
