The camera does not recognize the lens and an error message is displayed.

Follow the steps below if your camera doesn't recognize the lens and displays any of the error messages below on the screen of your camera:

• Check the Lens attachment.
• No Lens Attached.

Note: Refer to your camera's manual to complete any of the steps in this solution. Manuals are posted on your model support page.

Check the Lens

• Make sure that the lens is compatible with the camera body.
  Note:

  • Set the following if you attach the camera body to an astronomical telescope or other similar device:
    • Set the mode dial to Manual (M).
    • Set the Release w/o Lens option in the camera menu to Enable.
    • Set the Shutter lock option in the camera menu to Off: no lens.
  • Some Lensbaby™ lenses may attach to the camera body, however, they don't communicate electronically with the camera body. The camera can't recognize these lenses. We don't support the use of the Lensbaby lenses.

• If possible, try a different lens.
  Note: If the issue doesn't happen with other lenses, then the previous lens may require service. However, if the issue occurs with other lenses as well, then the camera body may require service.  Go to Product Repair. 

Check the Connection

Make sure to attach the lens properly. The camera can't communicate with the lens if the metal pins on the camera body and lens doesn't make contact. Follow the steps below to check the connection between the lens and camera body:

1. Power off your camera.
2. Detach the lens from the camera body.
3. Examine the metal contacts on the camera body and on the lens.

   

   • Make sure that the metal contacts are clean and nothing obstructs it.
     Note:

     • Use a dry, soft cloth to clean off any dirt off.
     • Make sure that nothing will fall off inside the camera body or the lens.
     • Don't touch the sensor of the camera.
     • Don't touch the mirrors in the lens.
     • Wipe lightly so as not to put pressure on the contacts.

   • Make sure the metal contacts are not bent. If any of the pins are bent, your device may need repair.  Go to Product Repair. 

4. Re-attach the lens to the camera body.
   Note: Align the marking on the lens to the marking on the mount on the camera body, then lightly turn clockwise until it clicks.

   

5. Power on your camera.
