I have OMD now and used to shoot with GRD starting w/ II, then III, then IV. I was a bit disappointed that the IV didn't offer a bit more than the III. Nice bokeh on the GRD is difficult, that was the main reason I sold it. I believe it should have offered a F1.4 or at least HD video. But for street shooting with deep DOF, it's the best there is. Ultimately I went with X100 and XPro1. The camera choices for street shooting is tremendous today compared to few years ago. GRD is losing its competitiveness.
