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.
