Update, but read this firstWhat's new
- 5.01 (28 May 2026): fixes part of the green AF frame not showing with the Expand Spot feature, and improves operational stability.
- 5.00 (3 Feb 2026): shooting information laid out for horizontal and vertical viewing; Spot XL and Custom 1-3 focus areas (and their Tracking versions); a larger menu display; both cards' remaining capacity during relay or simultaneous recording; USB streaming; Write Digital Signature for movies and Volume Photography License commands (both need a paid Sony licence); a fix for audio being recorded with Audio Recording off.
- Included from 4.00 (22 Apr 2025): the Security (IPsec) function and WPA/WEP Wi-Fi are no longer supported (use Access Authen. and WPA2 or WPA3).
Should you update?
Update, but read this first
Read first: Sony says some settings don't carry over from 4.00 or earlier, even from a saved settings file (Network Streaming, Cloud Connection, Access Authen., and some Custom Key and My Menu items), so write them down first.
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 only runs at 51% or more) and detach the vertical grip.
- 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.
Put the card in slot 1: only slot 1 reads the update. On 2.15 or earlier, update to 3.01 first, then 5.01: Sony says going straight to 5.01 gives an error.
