Nikon has announced firmware version 2.0 for its full-frame Z6 and Z7 mirrorless cameras, and it's all about autofocus.

The most notable upgrade is the addition of Eye AF, which is available when using the Auto-area AF mode. Nikon says that it will stay locked on eyes if the subject changes poses, or if they are partially obscured by another object. Switching between eyes and detected faces in the scene can be done using the multi- or sub-selectors.

The update has also improved AF performance in low light, extending the AF detection range from -1EV to -2EV on the Z7, and -2EV to -3.5EV on the Z6. If you're using the 'low-light AF function on these cameras, Nikon claims that the Z6 can focus down to -6EV, while the Z7 remains unchanged at -4EV.

Lastly, Nikon has added the ability for the Z6 and Z7 to shoot continuously with full-time auto exposure at the fastest burst rates: 12 fps on the Z6, and 9 fps on the Z7.

The update is now available for download on Nikon's website.

Firmware Upgrade Brings Further Improvements to the Nikon Z 7 and Nikon Z 6 FX-Format Mirrorless Cameras by Adding Eye-Detection AF, Improving AF Performance in Low Light, and Adding Auto-Exposure Tracking to the Continuous High-Speed (Extended) Mode

MELVILLE, NY (May 16, 2019 at 2:00 a.m. EDT) -- Nikon Inc. is pleased to announce the release of firmware Ver. 2.0 that will further enhance the performance of its full-frame mirrorless cameras, the Nikon Z 7 and Nikon Z 6.

Users will enjoy three main additional features following the Ver. 2.0 upgrade. These include:

  1. Eye-Detection autofocus (AF) for still-image shooting
  2. Extension of the low-light AF detection range
  3. Addition of auto-exposure (AE) tracking capability to the continuous high-speed (extended) mode

These enhanced shooting functions will further increase camera functionality and performance and are a response to customer feedback for new and innovative ways to capture and create.


1) Eye-Detection AF for still-image shooting

The new firmware offers Eye-Detection AF functionality that automatically detects and focuses on human eyes when using the Auto-area AF mode in both AF-S and AF-C. When the eyes of multiple subjects are detected, the multi-selector or sub-selector can be used to select the eye upon which the camera should focus. This enables precise focus on the eye of the intended individual, even when looking through the Electronic Viewfinder. This function is applicable even when the subject's face is partially covered by another object, or in the event when a subject is frequently changing their pose.

2) AF performance improvements in low-light situations

The new firmware enables even faster autofocusing when capturing photos and video in dark or dimly lit scenes, for both stills and video. It will extend the AF detection range*1 from −1 EV to −2 EV with the Z 7, and from −2 EV to −3.5 EV with the Z 6. In addition, the Z 6 will be able to autofocus with even darker scenes, as the available low-light AF detection range*1 will be extended*2 from −4 EV to −6 EV when the Low-light AF function is enabled.

  • With still-image photography in AF-S mode, ISO 100, f/2.0 lens, at 20° C/68° F.
  • The low-light AF detection range will remain the same with the Z 7.

3) AE tracking in continuous high-speed (extended) mode

With earlier firmware versions, auto exposure (AE) was locked with the first shot in a burst of high-speed continuous shooting at approx. 9 fps (Z 7) or 12 fps (Z 6) in continuous high-speed (extended) mode. Firmware Ver. 2.0 adds support for AE tracking in continuous high-speed (extended) mode, allowing the cameras to track exposure just as it does focus (AF tracking). This helps to ensure that all images captured with a burst of high-speed continuous shooting are in focus and exhibit optimal exposure, even when the brightness of the scene changes.

The new firmware can be downloaded (free of charge) from Nikon's Download Center at the following link: Users will be prompted to follow the instructions provided to successfully install the firmware.
