In addition to a new camera, a pair of teleconverters and a compact zoom lens, Nikon has also released firmware updates for its Z50, Z6, Z7 cameras and FTZ adapter.

Nikon Z50 firmware version 2.00

The most substantial firmware update is firmware version 2.00 for the Nikon Z50. In addition to support for the new Z-mount teleconverters and the ability to update older F-mount lenses via the FTZ adapter, firmware version 2.00 brings Nikon’s Animal detection autofocus (AF) as a custom AF mode. Nikon says this mode can detect the eyes and faces of dogs and cats when shooting stills (only faces will be detected when shooting video).

Additional improvements, taken from the changelog, are listed below:

  • 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.

You can download firmware version 2.00 and find installation information on Nikon’s support page.
