Nikon just announced firmware updates for the D5600, D7500 and D850. On the D850 this includes improving autofocus performance on sensor points on the edge of the viewfinder…now that is something every D850 user will want. Since I send my cameras in once a year for a cleaning at Nikon, the technicians will update any firmware that needs updating. But this is something I wanted to do today.
Installing new firmware is actually very easy. First, navigate to the link at Nikon, located here. Next, make sure the card slot you are using is the primary card slot…this is the slot you will use to install the new firmware.
Download the firmware from Nikon (they have instructions on the entire process on this page). Now insert a flash card into your computer, and transfer the firmware file from your computer to your flash card (i.e. on a Mac just drag and drop).
Make sure the file you move is the “D850_0110.bin” file, this is the file you need. It should appear at the top of the file list on your flash card folder by default. This file needs to be at the top to complete the update.
Next, go to your setup menu, and select firmware. Follow the simple instructions on the camera menu.
This takes about 5 minutes, and is simple to do. Better autofocus performance is something we all want!
