I couldn't find anyone else who had converted the Sony RX1 to IR or full spectrum so I took a bit of a risk converting it. Alan Burch (of Infrared Camera Conversions UK) was brave enough to give it a go and was very helpful throughout the process. He now offers this conversion service (if you have an RX1).
f/2.0 - 22
LHP-1 (not included)
Hotspot performance specifically is very good here, but there are some other IR issues that plague this camera. Click the below image to see my full review of the camera as well as more sample images.
