Phase Fresnel (PF) Lenses

This lens features a Phase Fresnel (PF) element. The PF element uses a

diffraction technique

standard glass elements, PF elements greatly reduce chromatic aberration,

allowing lenses much smaller and lighter than their ordinary refraction-based

equivalents, but are prone to colored ring flare (PF flare) when a bright light

source is in or near the frame.

• Colored ring flare in photographs can be reduced using the [PF Flare

Control] option in NX Studio. See NX Studio's online help for more

information.

• [PF Flare Control] can be used only with photographs. It is not available with

videos.

• NX Studio is available for download from the Nikon Download Center. Be

sure to always use the latest version.

Diffraction: Light has the properties of a wave. It bends around obstacles in its

path in a phenomenon known as diffraction. This causes a pattern of chromatic

dispersion opposite to that caused by refraction.
