I've created a lens profile today for the Canon FD 50mm 1.8 on a Canon 60D using the Fotodiox adapter. I sent it to Adobe for posting publicly. If anyone would like to download it in the meantime you can find it here:
I might have messed it up. It's my first time creating a profile and seemed to work fine for me in Lightroom. Let me know if there are any improvements to be made. I used f5.6 since that seemed to be the sweet spot on the lens and the imager was about 5 feet from the chart.
