Sony A7 IV Firmware Update v4.00

The latest firmware update for the Sony a7 IV is version v4.00

Important: When updating from Ver. 1.01 or earlier, you need to update to Ver. 1.05 first, and then to Ver. 4.00. Only upgrade to Ver. 4.00 after updating to Ver. 1.05. If you try to install Ver. 4.00 without updating to Ver. 1.05, an error will occur and you will not be able to update your camera.

If you firmware is v2.00 or higher than you can also download and install the latest firmware via Sony’s Creators App.

Firmware Download

You can download the latest firmware from your local Sony support website. The below links will take you to the correct page to download the firmware.

Firmware updates are not country specific, so you can still download a firmware from the US support site for example and install it on your a7 IV in Europe.

Version v1.05 Download

When updating from v1.01 or earlier you need to update to v1.05 first before updating to v3.02. If you are already running 1.05 or later then you can just install v3.02.

US: Sony Support

Version v4.00 Download

You can only install v4.00 if you already have v1.05 or later installed. You install will fail if you try to update to v4.00 directly from v1.00 or v1.01.

US: Sony Supp ort

Important Note: Since both v1.05 and v4.00 firmware downloads are called BODYDATA.DAT it’s important to delete the v1.05 download from your download folder and memory card before downloading v4.00. Otherwise your computer might rename the v4.00 download (if downloaded second) to something like BODYDATA-2.DAT which the camera won’t recognize unless you then rename it back to BODYDATA.DAT.

Firmware Installation Guide

Here’s a quick guide on how to install the latest firmware on the Sony a7 IV via memory card. If you are using Sony’s Creators App and your A7IV is already on firmware 2.00 or newer than you can also install the firmware via the app.

Important Notes

Use a fully charged battery & detach any battery grip.
Do not remove the battery during the update.
It may not be possible to update if the camera temperature is high, let the camera cool down first.

Step 1: Download the Software Update & Save to Memory Card

Download the firmware update and save this in the root directory of a freshly formatted memory card.

Step 2: Install the Software Update

Insert the memory card into slot 1 of the a7IV. Note: Only slot 1 will recognize the system software data.
Select Menu → Setup → Setup Option → Version and select Software Update.
Select Execute on the system software update confirmation screen and the update starts.

Notes:
- A Version Update X.XX → Y.YY message appears (X.XX = the existing version number, Y.YY = the latest version number).
- Do not remove the battery and the memory card during the update.
When the system software update starts, a black screen is displayed and the access lamp flashes. The access lamp flashes 1 time → 3 times → 5 times depending on the progress of the update. The update will take approximately 5-10 minutes to complete.

Notes:
- If the system software data copy is incorrect, The target model for the update file is incorrect. will be displayed on the monitor of the camera.
- If the access lamp repeats 5 long blinks (0.5sec. cycle) and 6 short blinks (0.25sec. cycle), the system software may not have been copied correctly to the memory card. In this case, remove the battery and memory card from the camera, and start over from Saving system software data to a memory card.
When the update is completed, the camera will automatically restart.

Step 3: Confirm the System Software Version

Select Menu → Setup → Setup Option → Version.
The system software version is displayed.

Step 4: Format the Memory Card

You should now format the memory card used to install the firmware before you start shooting.
