2. 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.
3. 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.
