As of today the Nikkor 300mm f/4E PF ED VR is the only Nikon Phase Fresnel (PF) lens.


Another Nikon patent for a layered BSI sensor (P6048482).


Interestingly enough this Nikon patent describes “variable-power optical system (ZL)” – maybe a reference to the rumored mirrorless Z-mount? Update: ZL could also mean zoom lens. This patent is for a 14-28mm f/2.8 VR DSLR lens.
