While taking some pictures during a late evening walk, I notced once more that the GXR AF is completely useless in low light. And with this is don't just mean that it is slow and hunts for over 2 seconds but it simply never manages to focus on anything. Anything I tried to focus on even something with enough contrast was too difficult and the camera gave up. This is pretty disapointing since the CX1 shows that Ricoh can produce a camera with fast and accurate AF in low light, unfortunately neither the GRD III nor the GXR come even remotely close. Hopefully Ricoh can improve this with a firmware update.
As it stands now the best thig is to just disregard the AF completely in low light and see the GXR with A12 module as a manual focus only camera.
This picture has been cropped to get the desired composition, I had no tripod so had to use what was available but could not get the framing I wanted.
