In summary

It should be obvious if you've read this far that the Sony a7R II is a significantly more capable camera than its stablemate the a7 II. They might look identical, but a quick run-down of just the major feature differences makes the distinction obvious enough: more pixels, better low light performance, 4K video, a vastly more capable autofocus system, fully electronic shutter, and more complete support for third-party lenses.

Whether these differences justify the enormous increase in price over the more basic a7 II is of course something that you have to decide for yourself. If you're primarily or exclusively a stills shooter and you don't have much need for continuous autofocus, the a7 II might suit you just fine. Its 24MP sensor isn't the best around, but it's not bad, and its 5-axis image stabilization system is very useful when shooting hand-held in poor light or at long focal lengths.

All this being said, if you're new to the Sony a7 system, the a7 II doesn't bring much to the table that you can't find duplicated or outmatched in other, competitive DSLR models. The a7R II, on the other hand, offers some unique features that we suspect will make it distinct from competitive DSLRs for some time yet.
