The Nikon D850 is a high-end digital SLR camera that offers exceptional image quality, thanks to its 45.7-megapixel CMOS sensor. However, like any electronic device, it is not immune to encountering problems. In this article, we will review the frequent error messages on the Nikon D850 and provide simple solutions to resolve them.

1. Error: "Memory card full"

When you encounter the message "Memory card full" on your Nikon D850, it means that the storage space on your SD or CFexpress card is exhausted. This problem can arise quickly, especially if you are capturing images in high resolution.

Solution:

• Check the free space on your memory card.
• Format the memory card if necessary.
• Consider investing in a higher-capacity SD or CFexpress card, especially one that is compatible with the high transfer speeds of the Nikon D850.

2. Error: "Lens error" or "Communication error with the lens"

This error message can be frustrating, as it prevents the camera from functioning properly. It is often related to contact issues between the lens and the Nikon D850 body.

Solution:

• Ensure that the metal contacts of the lens and the body are clean and free of dust or dirt.
• Remove and reattach the lens, making sure it is securely in place.
• Check if the firmware of the Nikon D850 is up to date.

3. Error: "Low battery" or "Battery exhausted"

Although the Nikon D850 is designed to be efficient in terms of power management, a low battery message may appear during long shooting sessions, particularly in live view or video mode.

Solution:

• Make sure the battery is fully charged before an important shooting session.
• Always carry an extra battery when you go out shooting, especially when traveling or for extended events.
• Opt for a Nikon MB-D18 grip, designed for the D850, to provide longer power supply.

4. Error: "Autofocus not working"

When the autofocus of the Nikon D850 is not working, it can be due to several factors. The AF system is extremely efficient, but it can sometimes become disoriented in certain shooting conditions.

Solution:

• Make sure the lens is correctly set to autofocus (AF) mode.
• Check that the focus mode is appropriate for your scene, for example, switch from "AF Point" to "AF Zone" or "Auto AF" for moving subjects.
• Check the settings of the Nikon D850, especially if the "Blur Reduction" or "Vibration Reduction" option is enabled, as this can interfere with autofocus in certain conditions.

5. Error: "Memory card error" or "Card not readable"

Another common error message on the Nikon D850 concerns issues with reading the memory card. This can be due to a defective card, a card not formatted correctly, or a card incompatible with the device.

Solution:

• Format the memory card directly in the Nikon D850 to ensure compatibility.
• Use recommended SD or CFexpress cards for the D850, which support high write speeds for continuous shooting.
• If the problem persists, try another memory card to check if the issue is with the card.

6. Error: "Flash sync issue"

The Nikon D850 is equipped with a built-in flash and multiple sync options for external lighting. An error message regarding flash synchronization may occur when using certain external accessories.

Solution:

• Check that the external flash is properly mounted and connected.
• Make sure the flash synchronization settings are correctly adjusted, especially the high-speed sync (HSS) mode if you are using compatible flashes.
• Try resetting the flash settings in the D850 menu to see if that resolves the issue.

Conclusion

The Nikon D850, with its high-resolution 45.7-megapixel sensor and rapid shooting capabilities, remains a powerful tool for professional and amateur photographers alike. If you encounter an error message, it is important to stay calm and follow the troubleshooting steps above. Most common errors can be resolved with a few simple adjustments. Remember that proper maintenance of your camera and using compatible accessories are essential to ensure its proper functioning.
