If both were released tomorrow, the only logical solution is to get both. Currently, shoot both; the Pro for wide to normal 14-35 with the OVF for fast framing. Walk around with the 14 on the Pro1, since it will allow manual focus from infinity to almost the front element at f8-11. After a while, I get used to composing in my mind's eye when I hold the camera down on the ground, up in the air, or snap a shot while looking innocent. The T1 is for normal to tele lenses. The 56 balances nicely on the T1 with the battery grip. Focus is fast enough for all but action shooting. For fast moving subjects, the Nikons come out with 16-35 and 70-200 lenses. Horses, cars, runners require the super fast, spot on Nikon focusing and 10 frames a second. Maybe the new software update will nail that work for the Fuji x-T1, but I won't sell my Nikons until I'm sure.
