Não, é pintura grafite mesmo, mais escura. Nessa foto ela me pareceu um pouco melhor:
E saiu a listagem do que vem no update de firmware para a XT-1, disponível em dezembro:
Exciting firmware update coming December 2014 (X-T1 Graphite Silver and X-T1 Black)
Fujifilm will release a free, comprehensive firmware update in December 2014 specifically for the new FUJIFILM X-T1 Graphite Silver and the original X-T1 Black that will give users exciting new features and controls to dramatically enhance their X-T1 shooting experience, including:
AF Area direct selection – Users can select the focus area with the 4-way controller, without pressing the Fn Key.
Function replacement for the AE-L/AF-L buttons – The currently locked AE-L/AF-L button function will now be interchangeable, depending on the user’s preference.
Focus Area size variability during MF – Users will be able to change the focus area in Manual mode during One Push AF with the AF-L button.
Macro Mode direct selection – Users will be able to directly turn ON or OFF the Macro function in Auto Focus mode to expand the distance measurement range to the short-distance range. This will be possible without accessing the pop-up menu screen.
Q Menu customization – The update will render the items and layout of the Q Menu, used for quick access of frequently-used items, changeable to the user’s preference.
Video frame rate selection – In addition to the existing 60fps and 30fps selections, 50fps and 25fps, as well as a 24fps selection will become available to users. 50fps and 25fps allow video editing in the PAL region, such as Europe and elsewhere, without converting the frame rate. The 24fps will offer movie-like video capture and play back.
Video manual shooting – Users will be able to select ISO sensitivity prior to shooting videos, as well as adjusting the aperture and shutter speed during video shooting.
Phase Detection AF support for One Push AF – With One Push AF, operated by pressing the AF-L button during manual focusing, the update will enable Phase Detection AF with quicker focusing speeds.
Metering area focus area interlocking – The update will enable users to interlock the AF area position with the metering area when spot metering is selected.
Expansion of the Program Shift setting area – The update will enable the current Program Shift, in which the low-speed side is 1/4 second, to be shifted to a maximum of 4 seconds.
Não fala nada sobre electronic shutter na XT-1 original - portanto, parece que aquela hipótese deles oferecerem upgrade do sensor pode virar verdade.
