MrTritium: My god, for a much lower price you can buy a Fuji X-E1 with the 23/1.4 lens!
Same equivalent focal length, same amount of light on the sensor, interchangeable lens, a viewfinder and more controls… I wonder who will be stupid enough to buy the RX1.
Comparing the RX1 with full frame DSLRs doesn’t make sense. Completely different size, weight, and features.
The RX1 should be compared to other big sensor mirrorless cameras. And in my opinion, the Fuji X-E1 is vastly superior.
This Sony camera does not have a Zeiss lens, just as described on the Sony website as " designed and PRODUCED in close collaboration between the 2 companies" Sony use the franchised name and they or some other t/p company make the lens to Zeiss design specs., [ it's still a good lens ] in the same way Panasonics 'Leica' lenses are not made by Leica.
This camera is much dearer than the Leica X2 and I don't believe there will be any real world difference in picture quality despite the larger sensor. Of course it has auto focus and other benefits but if only it had been an interchangeable lens camera with I/S then some of the hype would have been justified.
As they say "we shall see" ?
