N‑Log Recording
While N‑Log recording is in effect, Picture Controls cannot be
used, ISO sensitivity cannot be set lower than ISO 800 or to
values of from Hi 0.3 to Hi 2, Active D‑Lighting and high ISO
noise reduction turn off automatically, and photographs will
not be taken when the shutter‑release button is pressed all
the way down. The camera may also have trouble focusing;
this is not a malfunction. The subject will be displayed in the
monitor, not the viewfinder, regardless of the display mode
selected, and flicker or noise may be visible in the display.
Note that because HDMI output is not available when the
camera is connected to devices running SnapBridge or
Camera Control Pro 2, these applications cannot be used for
N‑Log recording.
