Will I be buying this camera? No, but I do have a the newer FujiFilm X-E1 with the 18-55 f2.8/f4 zoom lens on order. This camera has exactly the same sensor as the X-1Pro and is even a bit smaller and lighter, due to the lack of the Optical viewfinder (OVF). By the way, on the X-1Pro, I did hardly use the OVF and really like how the Electronic Viewfinder (EVF) works. Will it replace my full frame Nikon D800? No of course not. For the moment there is clearly room for both. The X-E1 will go on my travels whenever I need to go light. I do however believe that the D800 might be the last DSLR body I bought. The future of the mirror-less is surely exciting and I sincerely believe they will eventually replace most if not all DSLR bodies.
