Successsfulll!
I removed the internal hot mirror filter and recalibrate the auto focus of my Ricoh GX100. By doing this, I don't need to have long exposure and bring a tripod for IR shoots. If this doesn't make sense, go to

I use the hood adapter, 43-52mm step up ring, and put on either a 52mm hoya r72 IR filter or red colour filter for more colours. I'm going to order a Tiffen or bw hot mirror filter so I will be able to use the gx100 for taking normal pictures, but no rush at all
