Have you considered the original Q? If the lens and viewfinder are big deals to you, the Q has the same lens and a perfectly good viewfinder at a much lower price. You miss out on the sensor resolution and a handful of other features like weather-sealing and 4K video you wouldn't get with the GRIII anyway. These cameras also handle quite differently, you've probably thought about this but just mentioning it. I don't have a Q or Q2, but I'm currently considering both of them depending on my budget. I will probably go with the original and use the remaining money for something else.
