Clean up the Camera contacts

Check the camera body at the place where the lens fits with the camera. A speck of slight dirt, dust, or even clothing can cause a communication error between the camera and the lens. Check if the mount is clean enough and there is no damage to the contacts. For long term use, it is crucial to ensure that the mount interface is regularly cleaned.

You can even use the bulb blower and use the blowing option to clean it from the mounts. Never use the compressed air or blow from your mouth.

Use the Proper Blowing techniques

Ensure that you are using proper blowing techniques. Never blow form outside. Sweeping from the outside will make the dust particles to move further inside the camera. Use the same methods to clean the lens.

Do not touch any of the areas either on the camera or the lens. The oil or dirt from your fingertips can cause further communication errors on your device.

Inspect your Memory card

An incompatible memory card can also be a reason for throwing the error. However, do note that it may not always be accurate and can be used as one of the possible issues. There are cases where a card is failing for a few unexplained reasons. In such cases, it can be a good idea to check another memory card on the camera.
