Trade. Create.

The following main functions will now be available through the firmware update:

• Eye-Detection autofocus (AF) in stills mode
• Extension of the low-light AF detection range
• Addition of the auto-exposure (AE) tracking capability to the continuous high-speed (extended) mode 

Eye-Detection autofocus (AF) in stills mode

The new Eye-Detection AF function automatically detects and focuses on human eyes in the auto-area AF (AF-S, AF-C) mode. When the eyes of multiple people are detected, the multi-selector or sub-selector can be used to select which eye the camera focuses on, even when looking through the Electric View Finder. Once the photo is taken, the user can easily verify that the image is in focus by pressing the ‘OK’ button to zoom in on the eye that was the intended focus target.

Extended low-light AF detection range

The new firmware enables even faster autofocus when recording dark or dimly lit scenes, with both still-image photography and movie recording. It extends the AF detection range* from −1 EV to −2 EV on the Z 7, and from −2 EV to −3.5 EV on the Z 6. When the Z 6’s low-light AF function is enabled, the available low-light AF detection range* will be extended** from −4 EV to −6 EV, so it will be able to autofocus with even darker conditions.

Auto-exposure (AE) tracking in continuous high-speed (extended) mode

Previously, exposure was locked with the first shot in a burst of high-speed continuous shooting. Firmware version 2.0, however, 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 ensures that all images captured with a burst of high-speed continuous shooting are not only in focus, but also exhibit optimal exposure, even when the brightness of the scene changes during the burst.

The new firmware can be downloaded (free of charge) from Nikon's Download Centre.
