Yeah, well I went back to the XT1 for a while too, having decided it was good enough. But I still had an RX1 and it didn't take me long to decide to go all in. I didn't want to - I shot m43 and Fuji for long enough to know their charms and I was REALLY happy with them, fully satisfied, until I shot with an RX1. You shouldn't spend time with a sensor like that if you're not prepared to deal with the consequences. I wasn't, but after a while, I had to find a way to go all in. And, again, the D610, which is the bargain of the Nikon line, has the same sensor as that in the A7 and RX1, and it's DR leaves my Df in the dust. It's simply amazing. The Df is just really really really good. This particular scene was no problem for it, but I honestly don't think the Fuji would have had much problem with this one either. Where I ran into problems with the Fuji was usually blown highlights more than buried shadows. I could usually pull the shadows up well enough if the ISO wasn't too high. But I could get in trouble with highlights. And in the D610 sensor in particular, you can't believe how much information is hiding up there in those clouds... But it's not just shadows and highlights - there's something about the way these files handle all kinds of wierd effects. With lesser files, I'd have to fight to avoid all sorts of artifacts and halos and stuff playing with the Nik plug-ins. But with these full frame files, I can try just about anything, because they can handle just almost all of it....
