Should you update?
Update now
A fix update. Sony also notes that after updating, WPA and WEP Wi-Fi are no longer supported: use WPA2 or WPA3.
How to update
- Download BODYDATA.DAT from Sony's page (button below). You can also download it with Sony's Creators' App.
- Format a memory card in the camera (this erases it), then save BODYDATA.DAT in the root of the card. Don't rename it, and keep only one BODYDATA.DAT on the card.
- Use a fully charged NP-FZ100 battery: the update needs at least 51%.
- Put the card in the camera. On the camera: MENU › Setup › Setup Option › Version › Body, choose Software Update, then Execute.
- It takes about 6 minutes. Don't remove the battery or the card. The camera restarts by itself when it is done.
If the camera is hot, the update may not start: wait for it to cool down.
