Firmware version 3 for the Z 6/Z 7 added Animal AF Detection. Z 6/Z 7 firmware version 2 added Eye Detection Autofocus functionality as well as some other features. But, if you had purchased a Z 6 or Z 7 early on, you would need to update the firmware to take advantage of the newer features. If you bought one of the cameras new at that time, it shipped with the firmware updated. Later, the engineers were able to add new features. For example, when the Nikon Z 6 and Z 7 were announced, they shipped with a certain firmware version. Why should you update the firmware in the camera? If your camera offers a firmware update it’s usually a good idea to take advantage of it. Updates to firmware can fix problems like bugs or provide users with added functionality and features or advanced compatibility with other products like lenses or new media card formats.

Manufacturers design products with the intention that there will be regular firmware updates. Cameras have firmware, as do computers and all sorts of consumer electronics devices. What is firmware? Firmware is the embedded software that a device such as a digital camera uses to control certain hardware functionality.
