Aperture Series: Sony A7R with FE 35mm f/2.8 Sonnar ZE (Agapanthus Berries)

Is the A7R a Nikon D800/D800E replacement on an image quality basis?

Maybe, and maybe not: of some note are certain tonal transitions which caught my eye: excellent image quality overall but the aperture series shows one concern which is discussed in general terms on the Sony A7R file sizes page. It involves Sony’s lossy compression and tonal transitions.
