Nikon made a splash into the full-frame mirrorless  camera market with its Z Series. There are currently three different models in the line, the Z 50, Z 6, and Z 7, its most advanced version to date. All three models have received a firmware upgrade to improve camera performance.

Firmware version 3.00 for the Nikon Z 7 and Z 6 adds Animal-Detection AF, improves subject-tracking AF, and adds support for CFexpress memory cards. The Nikon Z 50 sees an update with its AF in movie mode with version 1.10. 

Nikon Z7/Z6 v3.00 features

  • Addition of Animal-Detection AF
    The Nikon Z 7 and Z 6 now recognize the eyes and faces of dogs and cats. When multiple animal faces or eyes are detected, you can use the camera’s left and right indicators to select the face or eye that the camera focuses on. When recording videos, face detection will be enabled.
  • Enhanced Functionality for subject-tracking AF
    Subject tracking for still shooting in AF-C mode has been modified to provide a more familiar operational feel similar to that of the 3D-tracking feature built into Nikon DSLR cameras. To enable the feature, hold the AF-ON button or half-press the shutter-release button to initiate. Subject tracking disengages when users take their finger off the button, causing the camera to switch back to the original focus point before subject tracking began. Additionally, the transition from the Auto-area AF display to the subject selection display can be assigned to a custom control button for a more customized experience. 
  • Support for CFexpress memory cards
    Nikon has added support for Sony CFexpress memory cards, select Type B CFexpress cards by ProGrade Digital and Lexar are supported.
  • Custom f2 settings
    Version 3.0 also adds NIKKOR Z lens controls support, like what's found on the NIKKOR Z 70-200mm f/2.8 VR S. Two lens Fn buttons, can now be assigned. The focus limit switch can be employed and autofocusing with manual override (M/A mode) is fully supported.

Nikon Z 50 v1.10 features

  • Improved AF Operation in Movie Mode
    The Z 50 sees an update in AF when recording movies in self-portrait mode. The feature will lock focus at AF-F mode allowing the camera to better maintain focus on a user’s face while recording video.
