gutsblow tweeted on a Cubic Lens Distortion Pixel Bender filter for After Effects from François Tarlier. It a port of the SynthEyes Lens Distortion Algorithm for matchmoving.
The built-in filter CC Lens Distort doesn't seem to have a Cubic Distort parameter for exact matching, but it does have better aliasing.
Update: there's now a version 2 of this filter that adds a Chromatic Aberration control -- it runs fine in AE but maybe not Pixel Bender Toolkit.
Update 2: there's another update.
Update 3: good news, this filter is also available through AE Scripts.
