Remove the rear lens cap and you'll see a row of metal contacts. Simply use a clean pencil eraser rubbed over the contacts.

The pencil eraser trick works although Canon repair say don't use this method yet behind closed doors they do the vary same thing. Just make sure you have cleaned the gold contacts well of eraser dust with a lens cloth not a tissue. The reason you should use a new clean eraser is because it hasn't been used for its intended purpose and you haven't just successfully transferred pencil lead, ink and bleach to the contact surface. Use a new eraser only and if the problem still hinders you then I would suggest upgrading your camera firmware which is a free download from the Canon site. As the camera can't talk to you the only way of communicating a problem is through error codes however there isn't enough error codes to cover all possibilities. This meaning that the lens connection may be what the book said but in fact it could be a battery connection problem as well OR if you have a battery grip the contacts there can also give a little head ache. Clean them all and then do the firmware update and you will be back into the photography in no time cheers have a great day

Have you tried cleaning the contacts? Taking out BOTH batteries? (There's a button cell as well as the main battery.) If you have a second lens you can test, i'd give that a shot first. Either way, probably need to have it replaced or repaired right away.

Finally, have you got the latest firmware version? The XS is currently at version 1.0.5, which was released in April of this year. You can download it here.

The flat printed cables inside the lens unfortunately develop small cracks over the years and this causes the lens to fail. The repair is NOT easy, you have to tear down the lens all the way to it's base components and replace the flex cable on the aperture diaphragm. The cable and the diaphragm are available online, but again it's not a simple repair and most people should not attempt it themselves.

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.

Might be that the aperture is stuck and you need to get the lens repaired (might cost more than a new lens.) Or it might just be bad contacts. Clean the contacts and try another lens before asking Canon or dismantling the lens.

Hi error 01 on canon 5d mk 1. With brand new 70-200 2.8? Have read there is an issue on portrait shots but I am unable at this stage to be sure if it has only been an issue for landscape horizontal use or...

Error 01 is generally associated with camera unable to communicate with lens. Could be contacts need cleaned; since lens is new contacts on camera are more likely starting point for cleaning. But, common issue is failure of something in the lens, but that seems unlikely as it is new ... but it could happen. You might search for other Canon Error 01 comments/solutions. Failing a solution from that, time to contact SigmaUSA repair to have them inspect/repair under warranty.

I tried using a 800mm lens with a 2x teleconverter on my canon digital rebel every time i press the shutter button i get err code 01 what does this mean

Hey there derf69, the error code "err 01" indicates the need to clean the lens contacts, which in your case you have several. I suggest you completely clean the contacts using a contact cleaning solution which dissappears completely. you can also use a clean eraser to effectively remove any resilient buildups. I suggest you completely disassemble your lens configuration, and rebuild, once all contacts on the lens and camera body have been cleaned. There is also a possibility that you may have an incompatibility problem. If the cleaning does not help, please let me know and provide the exact model name and number of your camera, lens, and converter. Good Luck

reset camera by removing battery completely for about 10 seconds.
otherwise, time for service.

you can use a contact cleaner sparingly, available from frys electronics or any other electronic reseller like radio shack.
good luck
