Nikon has issued an update for the D750 to firmware version C1.02. According to Nikon, the firmware update simply provides that “Camera operation is now more reliable.”
No additional features, notes or bug fixes are mentioned. You can download the update here on Nikon’s website.
My d750 has been acting strangely since I bought it. Aperture sticks and changing settings on the fly are quirky at times, I have done the update and since then have not had any issues. Glad ?Nikon has updated the firmware so quickly.
