Dustin has completed the Canon Rumors review of the Canon EOS 5DS R, a camera that a lot of Canon photographers asked for and is probably the most polarizing DSLR in terms of need that I've ever come across.
Do you need 50mp?
…. that is the conundrum of the 5DsR. It is a great camera, but it is also a niche one. If you need 50MP, it’s not only the best 35mm option; it’s currently the only one. But if you don’t really need 50MP, look elsewhere, as that amount of resolution comes with a cost. I suspect the biggest market for the Canon EOS 5Ds/5DsR twins will be in the bags of photographers who don’t use them as their sole cameras and are able to use them in the way they intended: special tools for specific jobs.
