Take off the lens and clean the metal contacts (the parts that connect to the same metal parts on the body) with isopropyl alcohol or methylated spirits.

Try cleaning the electrical contacts on the back of the lens and in the lens mount on the camera body.

Do you have another lens and/or camera body you can try? Does this lens work on another body, or does another lens work on this body?

reset camera by removing battery completely for about 10 seconds.
otherwise, time for service.
sounds like a processor board issue.
you can use a contact cleaner sparingly, available from frys electronics or any other electronic reseller like radio shack.
good luck

SOURCE: Error message communication between camera and lens is faulty

Your flex cable to the Iris is broken. Have a look at my gallery at http://www.pbase.com/barry_2718/efs1785mm I have the same symptoms. At 28 or 35mm it make work ok. try Av mode and f8 aperture to see if you get an err01 because the aperture does not move either. Sound like you may have been sold a dead lens I am afraid to say. There are lots of reports about this lens failing after 2 to 3 years of use.

Hi.

Problem is either the well known firmware bug, or a real problem in communication between lens and camera.

Do a firmware update ensuring that you read and follow all the indications in the page linked below. If you fail the firmware update the camera may not start anymore.

Here Canon firmwar update for EOS Rebel XS / 1000D

That will usually fix the problem, if it doesnt; check lens connector contacts and test using different lens.

Regards.

Ginko.

Getting a message that reads...communication between the camera and lens is faulty... What do I need to do


You didn't mention what camera brand you have but if it's an interchangeable lens this usually indicates either the contacts are dirty (you can gently clean with with a clean cloth or *lightly* rub them with a clean pencil eraser making sure the lens and camera body point down so nothing falls into them) or that a pen is broken. Another option is the contact on the lens has been damaged or a pin on the camera body is.

I've also had issues with aftermarket lenses (Tamron) on a Canon 7D because the tolerance of the 7D mount was very precise and the lens didn't fit as tightly as needed.

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.

Err 01....communication between lens and camera is faulty.Please clean the lens contact...this is the error message...please say a solution..


The contacts are the little gold coloured metal squares that touch between your lens and the body. Clean them with isopropyl alcohol (moistened glasses wipes work well) and see how you go.

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!
