Hi,
With the 550d 109, you can call SaveLensToFile (sub_ff019f70) and lenses data are saved on the SD card.
the resulting file is 'LENS00.bin' and contains data for Peripheral Illumination Correction, and maybe other things because each record is 0x370 bytes long.
please find a first script to parse this file
see also http://cpn.canon-europe.com/content/education/masterclass/peripheral_illumination_correction.do
such information was already in 400d, see below:
