Pulled the trigger and paid to have my brick IR-modded... also have a K-30 and Ricoh GR which I use more for typical photography, so finally decided to have the K-01 be a dedicated infrared camera. There is a gentleman named Isaac Szabo doing these conversions out of Arkansas who comes highly recommended, and the price was certainly right (search eBay!) You also send him a lens that you would be using (in my case a F 50/1.7) and the AF is recalibrated.
I've been going back and forth on whether to get the 720, 830 (b&w) or full-spectrum conversion, but I tend to like the look of R72/720 images best anyway (in b&w and false color) and like the idea of not messing with additional filters on the lens (full-spectrum). Anyway, will give a full report when it's sent back, typically a 1 week turnaround
