How to Update Your Fujifilm X Camera & Lens Firmware

Why should you update your camera’s firmware?

Fujifilm is known for its “Kaizen” philosophy when it comes to updating camera firmware.

Whereas other camera manufacturers may make you buy the next camera model to get new features or improvements, Fujifilm makes these available via firmware when possible, and often. Some of these features are huge and it’s almost like buying a new camera without buying a new camera!

And bugs happen – you won’t find a camera manufacturer that doesn’t have an occasional bug with their camera operation. This is the other main reason to update your camera firmware. You want to keep that camera running in tip-top shape, and new firmware releases will make it so.

How do you know if you need to update your Fujifilm firmware?

You can check your Fujifilm camera’s current firmware version by holding the DISP/BACK button when turning the camera ON. Note that you’ll need to have a memory card inserted in the primary slot to check the current firmware.

With the camera OFF, press the DISP/BACK button while turning the power on.

When you do this you’ll see the Firmware Upgrade screen. It will show you the current versions of both your camera body and lens firmware.

The Body shows firmware v4.20, but the Fujifilm firmware page shows v4.32 is the latest.

If you have a lot of lenses, and you’re not sure which firmware versions they have, you’ll have to do this process with each lens installed on your camera.

Go to the Fujifilm Firmware Update page to see the list of current camera & lens firmware versions. Compare the current versions with what you have.


They’ll also show the firmware release dates, which should help you readily identify if you need to update or not. Lens updates don’t happen nearly as often but take a peek anyway.

How do you update your Fujifilm camera firmware?

There are two different methods for updating firmware on Fujifilm X cameras:

  1. With your computer and an SD card (cameras and lenses).
  2. Via the Fujifilm Cam Remote app with Bluetooth-enabled camera models (camera bodies only – not lenses).

Ensure your battery is charged for all of them! Battery death during a firmware update can also result in camera death. The Firmware Upgrade screen will remind you of this before you start.

From an SD card

To prevent the possibility of any weird things going on, I’d recommend starting with a blank, formatted memory card. If you’re not sure how to do that:

  1. Plug the memory card into the camera (Slot 1 if it has multiple slots). Be aware that all photos on it will be deleted!
  2. Press MENU and navigate to SET UP (wrench icon).
  3. Go to USER SETTING.
  4. Select FORMAT.
  5. Select SLOT 1/Press OK to start the format.

The firmware updates are pretty small so don’t worry about if the card isn’t big enough. Pretty much any card purchased in the past 15 years is big enough – if you’ve managed to keep an SD card around for that long!

1 – Download the update

Navigate to your camera’s firmware at the Fujifilm Firmware Update page and click on it. The next screen will take you to the download page; agree to the license and download the .DAT file somewhere on your computer you can find it.

2 – Update the camera

Transfer the .DAT file to your blank, formatted SD card. Don’t put it in any folders, just keep it in the root directory.

Pop the SD card in your camera with the camera OFF. Do the same steps to check the firmware when you turn it on – press and hold DISP/BACK while turning it on. Press OK to go to the next screen and select if you’re updating the body or the attached lens.

You’ll be prompted if you really want to go ahead with the update. Battery charged? Firmware versions (old and new) look good? Highlight OK and press OK.

The firmware will be installed off of your SD card to the camera. The camera will let you know when it’s complete. Don’t touch the camera as this is happening. When it’s complete, the camera will prompt you to turn it off. Update complete! You can now reformat that memory card and use it for photos.

Using the smartphone app


You can also update your firmware through the Fujifilm Cam Remote smartphone app (iOS | Android). This is a much easier process than using an SD card. However, you can only do this for Bluetooth-enabled cameras.

This method also only works to update the camera body; lenses will need to be updated via the SD card.

When the app is on and connected to your camera via Bluetooth, it’ll automatically check for a current firmware update and let you know if one’s available. If it is, the first step is to download the firmware from the web to your smartphone.

1 – Download the update

To update the firmware, press Yes when the app tells you a new version is available. Then press Download to go to the License Agreement screen, presss I Agree, and wait for the download to complete.

2 – Update the camera

After the firmware is downloaded to your camera, press Update to proceed.

The next step is to transfer the firmware file to your camera. Since your camera is still connected to your smartphone via Bluetooth, press OK on the camera to switch to the WiFi network. In the smartphone app, press Join to join your camera’s WiFi.

Press Update to start the update. Then press OK on your camera to start the WiFi network. Come back to the app to Join the network. The transfer will start when the WiFi connection is complete.

Once the firmware file is transferred to your camera via WiFi, the next steps are very similar to updating the firmware via an SD card. The camera will install the firmware. Don’t touch anything! Turn the camera off when prompted.

And that’s it!

Just a word of practical caution: It’s usually best practice to wait a week or two after a new firmware version is released. People might find bugs, and Fujifilm does a good job of addressing them quickly, so maybe wait to see if that happens? It doesn’t happen a lot, and the bugs usually aren’t a nuisance, but every camera manufacturer falls victim to this occasionally.

Can I also update the lens via smartphone app?

No, sorry, that needs to be done via an SD card for now.

What excellent instructions! Thank you. Was ready to do the method with the SD card, but the bluetooth/wifi worked fast and I was done in just a few minutes.

Yep, the Bluetooth method sure makes things a lot easier!
