Well, many rangefinder cameras are easy to adjust for the vertical misalignment, for example all Leica M cameras without the front red dot are easily adjusted. Therefor I was wondering if the RF645 also supports this.
Look at he back of the camera. About 2-3cm right of the viewfinder is a small black plastic cap. Me thinks that's where the rangefinder adjustment is, but I don't want to risk breaking the cap, so wanted to hear of others' experience first :-)
