Don't get me wrong. The X100 is the best digital camera, I ever had. It's so close to my beloved Minolta CLE. My NEX-System was collecting dust, not more.
But: Sometimes I just miss the ability to change towards a longer lens. Last month I said to myself: You won't need something new. Only a fullframe CLE'ish like camera under 3k bucks would be worth buying.
Then I sold my NEX-7 and the lenses, as I heardly ever used them since I have the X100.
Then there came the X-E1. Okay, no FF, only EVF. If I really want FF and OVF there is still Leica out there. But the M's are too big and heavy to carry all the time. It's just that I know won't.
I decided to make an early order on the X-E1 in black. I try first with the 35/1,4, maybe the 18/2,0 will follow. I hope my M-Rokkor 28/2,8 will make my perfect zone focusing Streetmachine on the X-E1.
Last year I wouldn't have had any interest in a EVF-only camera. But since I use the EVF on the X100 more than 99 out if 100 shots, it must be sufficient for me. More so because the EVF of the new Fuji is the same OLED-Panel I know and like from my NEX-7. But it is behind the optical construction (2 aspherical lenses) of the X100, what I like even more. I don't care so much for the display, which is way better on the X-Pro (bigger + better resolution).
I hope it's not just G.A.S. and all the words above are bullsh...
