ethan the X-T3 is not going to have IBIS, nor will the crop sensor, no matter how new, outperform a full frame one where it matters like in low light. Not to mention Sony Eye-AF is several generations ahead of Fuji. Add to that, it will still use the same old weak battery as the X-T2.
At some point you have to be a little realistic.
Is it confirmed that it wont have IBIS? Is it confirmed it's using he same battery?
