How to Fix Blinking “Err” Error on Nikon DSLR Cameras

You went out and bought yourself a shiny new DSLR, but after you used it for a bit, the dreaded “Err” error popped up on the LCD of your camera, right? Do not be alarmed; it is possible that your camera has not been damaged, and there may be no need to send it back to Nikon, as is recommended in the majority of camera manuals.

This error occurs when the contacts on both the camera and the lens are contaminated with dirt and oil, which prevents the two devices from interacting with one another in the correct manner. The remedy is not too complicated; all you have to do is remove your lens from the camera, clean the contacts on the lens, and then clean the contacts on the camera. After that, reattach the lens to the camera and see the results. Does that sound very complicated? Do you worry about breaking your camera or scratching the lens? Then continue reading because if you do so, I will demonstrate step by step what should be done.

Therefore, here is the method broken down into steps:

1. Remove the lens from the camera and make sure that you are working in a clean atmosphere inside before you attempt to remove the lens from the camera. My preference is to do it in the bathroom late at night (when the children are asleep). If you have not yet learned how to remove a lens from your camera, now is the perfect moment to start practicing. Put the camera away and turn it off. To remove the lens from the camera, first press the lens release button, which is situated to the left of the lens when the camera is seen from the top, and then spin the lens in the other direction, clockwise. In order to prevent dust from entering the camera, immediately after the lens has been removed from its mount, place the black plastic cover that comes with the camera back on the lens mount.

2. Lens contacts need to be cleaned; there are a variety of various cleaning solutions available. However, the following method comes highly recommended by me: To begin, lather some soap into your hands and then thoroughly dry them. After that, pour some denatured alcohol (ethanol) onto a dry microfiber cloth of a light color, wrap it around your index finger, and clean each lens contact in a circular motion while being careful not to touch the glass on the rear of the lens. The following is a description of the appearance of the contacts on the Nikon 50mm f/1.4G lens:

If there is dirt or oil visible on the microfiber cloth, you will need to repeat the process described above using the section of the cloth that is clean. After you have finished cleaning the contacts, use the Giottos Rocket Blower and use it to remove any dust or debris that may have been left on the lens by the microfiber cloth.

3. To clean the contacts on the camera, first remove the black cap that is located on the camera lens mount. Next, using the clean side of the microfiber cloth, wash the contacts on the camera in the same manner that you did with the lens contacts. The following is a description of how the contacts on the camera appear:

Move from left to right and back again and again while holding the microfiber cloth while holding your index finger with your nails facing down. Repeat this numerous times. To ensure that the camera contacts are entirely free of dirt and oil, do the process once more, this time using the portion of the cloth that has been previously rinsed. Be cautious about getting this done in a reasonably short amount of time to avoid letting dust inside the camera chamber.

4. After ensuring that all of the contacts are spotless, reattach the lens to the camera by lining up the dot on the camera with the dot on the lens and then mounting the lens by turning it in the anti-clockwise direction.

5. Turn on the camera and shoot a few images after you have confirmed that the “Err” warning is no longer shown on the screen. The “Err” warning that was previously displayed on the camera should now be gone!

What should you do if the “Err” notification continues to appear on your screen? Change your perspective and observe how things turn out. In the event that nothing changes, your camera may be harmed; therefore, you should contact Nikon for assistance.
