Just to confirm, did you actually convert the camera to IR with a filter over the sensor, as opposed to simply putting an IR filter on the lens? If so, WOW, you've got money to burn!
I have an old Panasonic G3 that I had converted to an IR shooter several years ago, and love taking pictures with it. If I ever decide to convert my new and (to me) very expensive A7RII, it will be many, many years down the road!
