Changes from “C” Firmware Version 2.20 to 2.30

• [Save focus position] and [Recall focus position] have been added to the roles that can be assigned using Custom Setting f2 [Custom controls (shooting)] in the [CUSTOM SETTING MENU]. As of October 20, 2022, these options were supported with the following lenses: - NIKKOR Z 70-200mm f/2.8 VR S - NIKKOR Z 100-400mm f/4.5-5.6 VR S - NIKKOR Z 400mm f/2.8 TC VR S - NIKKOR Z 400mm f/4.5 VR S - NIKKOR Z 800mm f/6.3 VR S • The behavior of autofocus during memory recall has been improved to ensure that the focus position will not change in any focus mode even if the shutter-release button is pressed halfway while focus recall is in progress. • During remote photography with the ML-L7, the camera will now focus with every shot taken with [AF-C] selected for [Focus mode] if [Release] is chosen for Custom Setting a1 [AF-C priority selection] in the [CUSTOM SETTING MENU]. • Fixed an issue that sometimes resulted in the settings selected for Custom Setting f2 [Custom controls (shooting)] in the [CUSTOM SETTING MENU] not performing as expected in user settings modes.

Changes from “C” Firmware Version 2.11 to 2.20

• Added support for: - FTZ II mount adapters, - NIKKOR Z 24-120mm f/4 S lenses, - NIKKOR Z 28-75mm f/2.8 lenses, and - NIKKOR Z 400mm f/2.8 TC VR S lenses. • Improved face/eye detection performance and the visibility of subjects in pictures taken using an optional flash unit.

• Added support for NIKKOR Z MC 50mm f/2.8 and NIKKOR Z MC 105mm f/2.8 VR S lenses. • Fixed an issue occurring after the camera firmware was updated to version 2.10 that sometimes amplified the sounds generated by the aperture mechanisms when zoom or focus rings were rotated on certain F mount lenses connected via an FTZ mount adapter.

Changes from “C” Firmware Version 2.03 to 2.10

• A [Save focus position] option has been added to the [SETUP MENU]. If [On] is selected, the focus position in effect when the camera is turned off will be restored when the camera is next turned on. This option applies only when the camera is used with Z mount autofocus lenses. • Fixed an issue that resulted in the option selected for Custom Setting a2 ([Auto-area AF face/eye detection]) in P, S, A, and M modes being reset whenever Custom Settings for mode U1 or U2 were reset.

Changes from “C” Firmware Version 2.02 to 2.03

• Fixed the following issues: - Pressing the playback zoom in button to display a preview would cancel changes to [Set Picture Control] > [Hue] made using [NEF (RAW) processing] in the [RETOUCH MENU]. - Certain aperture values would not be selected when control rings for the following lenses were rotated to stop aperture down in movie mode: ▹ NIKKOR Z 50mm f/1.2 S ▹ NIKKOR Z 24-50mm f/4-6.3 ▹ NIKKOR Z 24-200mm f/4-6.3 VR ▹ NIKKOR Z DX 16-50mm f/3.5-6.3 VR ▹ NIKKOR Z DX 50-250mm f/4.5-6.3 VR

Changes from “C” Firmware Version 2.01 to 2.02

Changes from “C” Firmware Version 2.00 to 2.01

• Fixed character display issues that occurred when Korean or simplified Chinese was selected for the language item in the camera menus. No update is required if the language item in the menus for your camera does not list options for Korean or simplified Chinese.

Changes from “C” Firmware Version 1.11 to 2.00

• With the addition of an [Animal detection on] option to Custom Setting a2 ([Auto-area AF face/eye detection]), face/eye-detection AF is now available with dogs and cats; when this option is enabled, the camera will now detect the eyes and faces of dogs and cats (in movie mode, only faces are detected). [Animal detection on] is selected automatically when the mode dial is in the SCN (scene mode) position with [Pet portrait] selected. • Added support for Nikon Z mount TC-1.4x/TC-2.0x teleconverters. • Added support for F mount lens firmware updates. F mount lens firmware updates are supported from FTZ mount adapter firmware version 1.10. • Changed some of the f/-number values displayed when exposure is adjusted in steps of 1/3 EV (f/1.2 is now displayed as f/1.3). As of July 21, 2020, this applies to NIKKOR Z 58mm f/0.95 S Noct lenses. • The bracketing increment is now properly applied to photos taken with exposure locked during [AE bracketing] in [Continuous H (extended)] release mode. • Release-priority is now enabled if AF-S [Single AF] is selected for [Focus mode] when AF-ON is assigned to the AE-L/AF-L button. • The following improvements have been made to subject tracking: - Users can now switch between the auto-area AF and target selection displays using a custom control such as the Fn1 button. - The behavior of subject tracking when AF-C is selected during still photography now more closely resembles that for [3D-tracking] on digital SLR cameras. • The conditions for displaying the prompt suggesting the use of the flash have been reviewed and the prompt is now displayed under more appropriate conditions. • Fixed the following issues: - The crop selected for “tall” (portrait-orientation) pictures using PictBridge would not be accurately reflected in the printed image. - In rare circumstances, autofocus would not engage if a NIKKOR Z DX 16–50mm f/3.5–6.3 VR lens was extended at the same time the camera was turned on.

Changes from “C” Firmware Version 1.10 to 1.11

• Added support for the Fn2 button found on some lenses.

Changes from “C” Firmware Version 1.00 to 1.10

• Added support for the focus limit switch available on certain Z mount lenses (as of February 12, 2020, only the NIKKOR Z 70–200mm f/2.8 VR S). The lens Fn2 button is not supported. • Movie footage shot in self-portrait mode is now filmed using AF-F (full-time autofocus), regardless of the option selected for autofocus mode.
