radissimo: I always cheer to underdogs,so I am very happy that Ricoh outperforms Nikon in many ways...I am wondering how would be the picture quality with also pocketable SONY RX100 @28mm with f1.8 like? I know that GR is more user friendly,but again they have many things common:*pocketable,same size and weight*good and fairly bright 28mm*fixed screen, no EVF/OVFcan be RX100 more flexible with similar IQ?
This laboratory JPEG spec is meaningless to me. I only shoot in RAW, and seldom at base ISO. If you want to obsess over JPEG IQ at base ISO, why not just stick with a smartphone? If you're interested in a comparison that approximates real-world use (or at least the way I use the GR), go the Studio Scene Comparison (RAW) page for DPReview's Ricoh GR review, and replace one of the other cameras being compared to GR with the RX100. Download the JPEGs for the GR and RX100 and compare them in separate windows at full magnification, or just move the little crop window around to view close-ups of different parts of the studio scene image.
If you can't see the obvious IQ superiority of the GR (and the Coolpix A) over the RX100 IQ, then I suggest you have your eyes examined.
My previous compact camera was the RX100. I loved the RX100 and the IQ was very good compared to any compact camera I'd owned. But from the start I didn't like how it felt in my hand. Too slippery and not very comfortable to grip. I bought Richard Franiec's custom grip for the RX100, and that helped.
The RX100 performed well, and its AF was very fast in bright light, only slightly less fast in low light. Then I noticed that I was always shooting the RX100 at its widest angle, never zooming in, and I was attracted to the GR's APS-C sensor and what I had read about how good it feels.
So I sold the RX100 and bought a GR, and I couldn’t be happier. I've never owned a compact camera that feels so right in my hand and so thoughtfully designed for serious photography. The GR inspires me to be a better photographer so that I can take full advantage of its potential. And the GR IQ beats the RX100's. The only way the RX100 is more flexible to me is that it has a zoom lens. I love the GR more.
rusticus: good camera - unfortunately ugly - I do not buy
Your loss. Beauty in a commodity, for me, is determined by how effectively an item fulfills its intended purpose, and this is one of the most beautiful cameras I've ever owned.
