Nikon has released a new firmware update for its flagship full-frame mirrorless camera, the Nikon Z9. Firmware version 5.10 adds a slews of videocentric features and enhancements to the top-of-the-range camera that are squarely aimed to address the needs of professional-level videographers. Top of the bill is a new shutter mode that allows the user to set the 'shutter angle' to one of 15 steps, ranging between 5.6° and 360°, when shooting in Manual exposure mode.
We explain what shutter angle is more fully here, but it essentially controls the amount of time the shutter is open for each frame of video, and enables videographers to set the amount of smoothness verses the amount of blur in their footage. The new control eliminates the need to select a shutter speed whenever the frame rate is adjusted, allowing users to always achieve optimal motion blur at the desired frame rate.
