How to fix error 001 in canon lens


The Canon Err 01 is called Lens communication.
The lens has lost communication with the camera, or vice versa. This can be caused by dirt or grease on the gold coated contacts. On the lens or in the camera.
Try cleaning the contacts, with a dry cloth or cotton swabs. Don't use any sharp tools or force. To pinpoint where the error is, you could try to place another lens. If the error disappears most likely the first lens caused the problem. If the error stays, you should suspect the camera.
If you only have the problem with one lens, and the contacts are clean, contact a certified Canon repair centre.

Busy and or Error 01


For error message 01 the manual says: Communications between the camera and lens is faulty. Clean lens contacts.
Solve: Clean the electrical contacts on the camera and lens and use a Canon lens.
SO if you are using a different lens or a non Canon lens this could be what is wrong.

If you never changed a lens, it still can be that something went wrong in the communication between the camera and lens. Just careful remove the lens and with a dry and lint free cloth, clean all contacts on the lens and in the camera. While working on the lens, close the camera with the camera cap, or put the camera face down.
Don't use anything sharp while working on a lens or a camera.

So, have you cleaned the contacts as you were advised? You do this by removing the lens and cleaning the contacts on the camera body and on the lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

Error 01


Error 01 is about the communication of the LENS with the camera. Please try to re-attach it and make sure it is correctly fitted. Also you can remove the lens, start cleaning the contacts, put it back in place again and then test.

Good luck!

What does error 01 mean


Error 01: A communication problem between the lens and the body. Try cleaning the the area between the objective/Lens and the body. If that doesn't work, try another lens. If that doesn't work, try the first lense in another body, and if that works, it's most likely the body that's broken.

Canon err 01


This error means "Communication between the camera and lens is faulty. Clean the lens contacts." If you are using the same lens on both cameras, the problem is with the metal contacts on the rear of the lens where it communicates with the camera body. You can gently clean these contacts by using a clean pencil eraser. Make sure you hold the lens "bottom down" as you clean it so that the eraser debris falls to the table instead of inside the lens!
