Sony RX1 in-depth review by Richard Butler and Lars Rehm at DPReview: "If a fixed 35mm lens will fulfill any of your shooting requirements, then there's nothing to touch the RX1."

The Sony RX1 could be the ultimate 'Decisive Moment Camera' if it wasn't for some major niggles, like the lack of a built-in viewfinder, the subpar AF system, and that horrible orange bling ring around the lens. Common Sony, this isn't  a Hyundai Coupe, the owners of this camera already know they got a '35mm full frame CMOS image sensor' camera, no need to have a screamy text reminding them of it.

"At the start of this review we asked if the RX1 was a good enough camera to play in the same league as Leica. The answer is yes. The lens is excellent, as is the sensor (something that's not been true of digital Leicas so far), meaning it'll more than hold its own against the M-series cameras in image quality terms, even if it's not quite as engaging as a true rangefinder. Or, put another way, it's arguably the camera the Leica X-series aspires to be.

There are plenty of photographers who are likely to appreciate a camera with a fixed prime lens, precisely because it offers something that interchangeable lens cameras don't - in terms of size and dedication of purpose. So, if what you want or need is a fixed 35mm full frame camera, then the RX1 not only offers you that - it also offers a camera you can really love. And its combination of image quality and size make it one that will allow you to get photos you wouldn't get with any other camera."
