I'm interested in converting my E-P1 into a full-spectrum (well, fuller than just visible anyway) camera by removing the infrared hot mirror / filter from the front of the sensor. I realize you can get it done for about $350 from Spencer's camera, but I'd be interested in trying it myself if I could source a piece of clear glass to replace the filters. Some instructions for getting the camera apart and removing the filter online would be really useful too, so I can get an idea of how difficult it might be before beginning. I really don't mind doing this kind of thing myself and I have the right tools, but I don't just want to go in blindly. Also, can you get filters for removing IR and UV when you want to do normal visible light shooting with a clear-filter camera? Thanks for any help you might have.
