Hi ycp13, thank you for the compliment Its tough to explain why I like it as well. This was edited in LR5, and shot on the GRD4's B&W High Contrast Mode. I would love to get my paws on the GR, but my wallet does not agree!
I understand your lusting for the GR it's a wonderful camera, but the GR IV is an excellent camera in its own right. That small sensor and lens combo really produces some excellent gritty images that are well suited to street, I miss mine dearly and am now on the hunt for another.
