Several months ago, I rented the absolutely amazing full frame Sony RX1R II and took it to the NYC streets for the weekend. It was the beginning of summer. The camera handled brilliantly. It was fast to focus, it was small, stealthy and I just couldn't get over how vibrant and beautiful the raw pictures were that I got back from it. Coming from a Nikon DSLR, I was able to handle and get used to the controls quite quickly (although there's a LOT of information and settings in the the menus) but I shot manually at mostly F2 all day and my hit ratio of in-focus shots was amazing. I don't have this camera yet, but I'm definitely planning on getting it at some point in the ear future.
My time spent in New York City with the Sony RX1R camera.
