Shot a soccer game at night with the 250+1.4x and I'm amazed. Like stadium lighting is crap, but ISO4000 & 1/1000th at 8fps, tracking pro's at full sprint, it's no R3/Z9, but for 102mp results. The CFe card was keeping up with things, never missed a shot due to the memory card buffer.
Damn you Fuji, I'm supposed to spend this money on something else.
