Great question . Maybe the only reason since really nothing changes in the A7r file except size it's just a easier comparison to see what the A6000 is doing given the exact same framing. Not really should I use one over the other but just more clear to see the A6000 given the same crop. Now agree with you why would I use crop mode on the A7r over the A6000 well I would not now since I do have the APS sensor. Before I had just the A7 and A7r and on one gig was forced to use crop mode. So the reason I bought the A6000 was I get a full 24mpx sensor instead of reduced A7 or A7r file size. Now I have the A6000 on board and a A77ii on the way than I won't have to use crop mode. In this test it's far easier to see and identify the differences since it's exactly the same framing and far easier to spot what I need to do to bring the A6000 into the fold of the A7r.Guy
A question, just because I have no idea of the answer, if you are using the A7r in crop mode, aren't you forcing it to be basically an aps sized sensor? In which case, why would there be a difference between a crop A7r and the A6000, you've effectively made them the same? Wouldn't the test be better to upres the A6000 file to match the A7r? That way you'd see what the differences are when wanting to match files, basically as you're not using the A7r in crop mode. I'm guessing the advantage of the A6000 is the af speed or reliability otherwise there's no point having it, just use the A7r in crop mode. Matching the A6000 file to a reduced A7r file just doesn't seem to make much sense to me, especially if you aren't planning on using the A7r in crop mode.
It's quite possible that I just don't get it!

Maybe I should have been more clear on that point why I did it this way but more for convenience and identifying things better. I think it helps others see just how good the A6000 is much better too since there is no effect on changing the A7r except the file size. If I was testing noise and some other things sure test would have been diffrent.
For me also is getting a handling on the raw processing better too since I can match easier seeing the exact framing. So bottom line more a convenience and identity method more than this cam versus that cam. Those tests I hate doing
