Thanks for the info and link. I am planning to convert the X-pro 1 when the X-pro 2 comes out. A shame about the 18-55 I really like that lens.
I found these two places on the (in addition to the one in your link)
Kolari Vision Infrared Conversion Service and IR Photography Cameras
Spencers Camera & Photo Digital Camera Infrared (IR) Conversions, Modifications and IR Photography :: Welcome
I have a 5D converted now, and really want the option of the live view, Infrared is a really nice change, the 5D was done at life pixel and if I remember correctly it kicked in at 670nm.
