Review Excerpt

Significantly sharper, more detailed JPEG images than those from the RX1; JPEG processing appears to minimize moire and aliasing artifacts; Same price as the RX1; Full-frame, 24-megapixel compact camera with fast Carl Zeiss Sonnar 35mm f/2 T* lens; Blazing fast autofocus; Impressive image quality that rivals (and sometimes surpasses) full-frame DSLRs.
More prone to moire, aliasing and false color than the RX1; Only subtle improvement in sharpness in RAW files; Fixed-length lens limits shooting flexibility; Viewfinders (optical or electronic) only available as optional accessories; Extremely expensive for a compact camera.
Read our Sony RX1R Review

Highest resolution Micro Four Thirds camera yet; Great high ISO performance; Very fast autofocus; Fast burst mode with deep buffers; Impressive Dual I.S. system; Great 4K video.
No built-in flash; Slow buffer clearing; Below average battery life; Limited I.S. for 4K video.
