Sean Reid is reviewing the Leica T. He has provided a comparison to the GXR with Leica M mount using 21mm RF lenses

Both cameras use APCS sensors. The resolving power of the GXR does well against the Leica.....
Are you still actively using your GXR or is something else beginning to replace it?
The T sensor is of the same family as the Sony NEX 5n/6 sensor, and the one in the Leica X2 and X Vario. It was always pretty closely matched to the Ricoh GXR sensor, so no surprise there.
I still have my GXR, but the M9 pretty much replaced it for M-mount lenses.
I wasn't happy with cropped formats for the R-mount lenses so a Sony A7 has taken over that duty now.
