I've gone full circle myself, going from a NEX-6 to an XE-1, to now a RX1. Though I did get a great deal on a used NEX-7 to help build up my manual collection for the anticipated NEX-7 update or the FF-NEX.
the XE-1 just didn't fit with me. I bought it, tried it with the kit zoom and even ordered the 35 1.4 but something with the camera didn't fit me. Maybe it was the grip, but even after buying the Fuji grip it wasn't comfortable. The EVF lag, the lower resolution rear screen, even the cheesy graphic when deleting files. The JPEGs were really nice OOC, but it felt hollow and empty.
The RX1 I bought like new from Amazon for almost $700 off retail, so while still expensive, it was a pretty good deal. It feels substantial. The RAW files are tremendous, the pop that the Zeiss lens has is great. But after using it for almost a month I understand its limitations. I don't like that peaking only works in magnified view. While I do like the leaf shutter, I don't like that it doesn't have a remote shutter option. I've gotten used to the grip. Battery life could be better. I don't have the EVF so I can't comment on its quality. While I do like the 35mm lens and used a Zeiss 24 on the 6 when I had it, I do miss wide angle shots. The lack of tilting screen does bother me. And for some reason knowing that the camera is so expensive I feel like I need to be way too careful with it. That's not to say that I throw my gear around, but I do like to not have to feel like I should be wearing surgical gloves.
I did pick up a EOS M for the wife and while its a nice camera for her, I could never make it my main. The lack of manual control, the spotty AF, the lack of good manual focusing tools, etc make it a green box camera that's an improvement over her old P&S.
All this has brought me back to buying a NEX-7 for a really good deal, adding a few Speed Boosters and picking up some good quality lenses. I just picked up a C/Y Zeiss 50 1.7 for a great price and will pair it with a Speed Booster. I'm awaiting the NEX-7 replacement and which point ill sell the newly acquired 7 and not take that big a loss or the long awaited FF NEX.
