Nikon has released the latest firmware for Nikon Z7 and Z6, their full-frame mirrorless cameras. Version 2.0 is said to further enhance their performance with the main features being eye-detection AF (AutoFocus) with still-image shooting, extension of the low-light AF detection range and addition of AE (AutoExposure) tracking capability to the continuous high-speed (extended) mode.
Eye-Detection AF with still-image shooting automatically detects and focuses on human eyes in the auto-area AF (AF-S, AF-C) mode. If there are multiple human subjects in a shot, the multi-selector or sub-selector can be used to select the eye upon which the camera should focus. This allows focus on the intended individual even when looking through the Electronic Viewfinder. It also works when the subject’s face is partially covered by another object as well as when their pose changes. Once clicked, the user can directly zoom in on the eye and press the ‘OK’ button to check if it is indeed in focus.
Faster autofocusing occours when capturing dark or dimly lit scenes both stills and videos. The low-light AF detection range extends down from −1 EV to −2 EV with the Z 7 and from −2 EV to −3.5 EV in the Z6. Additionally, Z6 will also be able to autofocus with darker scenes as the available low-light AF detection range will be extended from −4 EV to −6 EV.
Earlier auto exposure was locked with the first shot in a burst of high-speed continuous shots happening at approximately 9 fps in Z7 or 12 fps in Z6 when using continuous high-speed (extended) mode. Now support for AE tracking in continuous high-speed (extended) mode has been added, enabling the cameras to track exposure just as it does focus (AF tracking). This ensures all images captured with a burst of high-speed continuous shooting are in proper focus and exhibit optimal exposure even when the brightness of the scene changes.
The new firmware can be downloaded for free from Nikon’s Download Center where users will be prompted to follow the instructions provided to successfully install it.
