Extensive review on the SONY RX-1. Mostly great and some not so good. Bottom line is that it is a groundbreaking camera that can more than compete with the best.

Performance, optics and image quality -- oh my!
Beyond its ground-breaking size, what really thrills me about the Sony RX1 is its image quality -- and its phenomenal lens. Ultimately, it all comes down to the pictures a camera can deliver, and the RX1 delivers in spades across the full spectrum of lighting conditions and subjects. Image quality isn't just good, it's exceptional. Having a sensor derived from that in the Sony A99, this comes as no surprise: That camera takes great photos as well, and the RX1 more than matches it. Whether it's due to its extraordinary lens, or to a weaker (or no) low-pass filter, images from the Sony RX1 are noticeably sharper than those of its translucent-mirror big brother at low ISOs, and significantly so at higher sensitivities where better noise-reduction processing could be playing a role.
What's remarkable to me is just how well the Sony RX1 stacks up against the best the field has to offer. (See the image crops below for specific examples, or help yourself to our Comparometer to compare all our test images, to your heart's content.) And when I say "the best the field has to offer," that's without limitation. Images from the RX1 can be put up against those from literally any 35mm-sensor camera currently on the market and they hold their own, if not better the competition. It's no surprise that the 36-megapixel Nikon D800 out-resolves the RX1 at low ISO, but the D800's smaller pixels exact a price at higher ISOs, where the balance tips in favor of the RX1 again.
