Question
Why does the camera’s indicator light keep flashing during continuous shooting, and why can’t I continue operating?
It may be due to an incompatible SD card or a slow write speed. Please refer to the information below for troubleshooting:
Use the right storage card
For camera storage cards, it’s recommended to choose reliable brands such as Sandisk, a globally recognized flash memory product supplier. Additionally, select the appropriate specifications based on your usage needs.
For instance, it is recommended to use a UHS-II specification SD card for continuous shooting or capturing a large number of RAW images in a short time.

Using slower write speed cards like class 4 or class 10 may require some time to complete saving after pressing the shutter.

When recording high bitrate videos, be sure to use storage cards with a video speed class of V60 or higher.
If you use a slower write speed card while recording video, the recording may be interrupted or fail to write during the recording process.
Even if you use a speed class V30 SD card, if the bitrate is set too high, recording may not be possible. In this case, please use a V60 or higher SD card.

If the write speed is slow, even if you turn off the power, the screen will not turn off and will remain in writing status, but will not accept any other operations at this time. This is a normal phenomenon and not a malfunction; it can be used for emergency shooting, but we do not recommend using slow write speed SD cards.

Additionally, Fujifilm would like to remind everyone: try to choose original lenses, original batteries, and other original accessories to ensure the normal use of your camera.

Use original batteries
Many counterfeit batteries differ in shape from Fujifilm’s original batteries, and many lack adequate safety mechanisms, such as protective devices. Using such counterfeit products may cause the camera to malfunction, or even lead to failures, abnormal heating, liquid leakage, explosions, or fires.
In such cases, not only could the digital camera be damaged, but it could also lead to serious incidents such as fires or burns. Therefore, please use Fujifilm’s original rechargeable lithium-ion batteries, which have been designed with performance and safety in mind.

Use original lenses
Some cases have shown that users have experienced scratches on the camera body and motherboard damage due to using third-party lenses on certain models.
To ensure the image quality output and compatibility of various functions of the camera, Fujifilm recommends that you use original XF/XC/GF series lenses to achieve optimal performance from your camera.

Finally, Fujifilm would like to remind everyone again to use original lenses, accessories, and batteries, and to use SD cards of corresponding levels from professional brands to ensure the safety of your equipment and data, and avoid losing a lot due to small issues.
