Nikon released new lens distortion control data with a new firmware update for the D90, D3100, D3200, D5000, D5100, D7000, D4, D800 and D800E cameras. This was probably the rumored firmware update I reported last week. The L firmware update provides corrections for lens barrel and pincushion distortions. You can see the complete list of supported lenses and the download link on nikonimglib.com. Installation instructions can be found here.
