I have an XE-2, current lens are 18-55, 27, 56, 60. I am still on the fence over which telephoto zoom, but leaning towards the 55-200, as much for its smaller size and weight as the cost. Others on my list:
18 f2 to complete smaller prime collection
35 f2 " " " " " "
14 F2.8 or 16 F1.4
120 Macro with 1.4X converter
Hope Fuji comes out with a 200 prime, F4 would be fine for me
