What’s New in Sony FX6 Firmware 6.02?

While minor in terms of total feature additions, firmware 6.02 delivers an essential stability improvement for dual-card recording workflows.

Changelog Highlights

• Dual-Slot Backup Fix: Improved stability during simultaneous dual-slot recording. Resolves a rare issue where an error occurring on one media card could cause recording to stop on the backup card as well.
• Includes All v6.00 Features: Retains all major functionality introduced in major release 6.00, including the BIG6 home screen interface and updated display layouts.

How to Install the Firmware Update

Updating your cameras takes approximately 8 minutes. Follow these official guidelines provided by Sony:

1. Download the version 6.02 firmware update file from Sony’s official support page.
2. Format a compatible SD card or CFexpress Type A card inside your Sony FX6.
3. Copy the downloaded update file directly to the root directory (top level) of your memory card using a card reader.
4. Crucial Step: Insert the card containing the update file into SLOT B ONLY. The FX6 will not recognize update files loaded into Slot A.
5. Connect the camera to continuous AC power via the AC adaptor (required by the camera system before initiating the update process).
6. Turn on the camera, navigate to MENU > Maintenance > Version, and select Version Up.
7. Follow the on-screen prompts and wait approximately 8 minutes for the update process to complete.

Should You Update?

Yes—especially if you shoot live events, weddings, or commercial interviews where simultaneous dual-slot recording is mandatory. The core purpose of backup recording is to guarantee redundancy if a media card fails; eliminating the bug that caused both slots to halt ensures true dual-card protection. If you only ever record to a single card, the update is less urgent, but installing it remains best practice for long-term system stability.
