10 years ago, maybe even 5, ISO 1600 was considered high ISO. I'm not sure that's true anymore. Any modern camera with a sensor that size can get a perfectly usable print from 1600. But I do agree with you that the Fuji X sensor is quite brilliant in regards to high ISO. 3200 is perfectly usable, and 6400 can be as well under the right settings. Nice shot and glad you're enjoying your new camera. I am too.
