Good colors, lots of detail and little noise up to 6400 ISO (though Fujifilm's 6400 ISO is closer to 4000 ISO in other cameras). The camera adjusts the white balance pretty accurately in all kinds of conditions.
It has a huge viewfinder with a 0.77x equivalent magnification. The size of the viewfinder allows for additional functionality such as displaying an enlarged image next to the overall image and turning the image to portrait view when the camera is turned sideways.
The camera will automatically adjust exposure. ISO and shutter speed is ignored. And so is exposure compensation past +/-2 EV. There's also no way to adjust aperture during recording, it has to be set before you start shooting.
