In an effort to avoid spending tons of money, I continue to long for a landscape camera that could match or come close to the 645D in terms of IQ. And so with that in mind, I decided to see what I could wring out of the Sony A7R in spite of the fact that it uses the same sensor as the D800E and seem to score the exact same on the DxO scale.
That being said, what was interesting is that I was able to consistently pull up more detail using Raw Therapee in the red channel with the A7R RAW files than I could with the D800E ones. To which I'd add, I'm really not sure why that is at this point though I'm confident that we'll hear more on this as time goes on.
Anyways, without further ado, here are some of the files I was working on. Though I must caution, that I re-sized the A7R in my effort to help compare details between the two systems. And so I wanted to put out there that this was done purely for my own use rather than distorting results etc.

In closing, I won't bother posting a conclusion as I think the images speak for themselves. Though I will say that I am thoroughly impressed with what Sony has done with there first mirorless FF body on the market(congrats).
