I recently bought a Nikon D600, 50/1.8G, and Sigma 35/1.4. Both of those lenses are fantastic, but after using the Fuji X-E1 these past couple weeks, I sold off the Nikon kit. Horses for courses, of course. I don't shoot sports, ultrawide, tele, much off camera flash, wildlife, or any number of things where the Nikon might do better. If I want to shoot very low light or shallow DOF, the Fuji does both of those enough for me. Plus the Fuji scores 100x higher in the all-important "want to use it" category. So goodbye again, Nikon. I'm sure I'll be back some day!
