Hi,

I'm Ben and -- hopefully -- I can provide some meaningful assistance.

This is a common problem with Canon SLR cameras. My suggested remedies are:

  1. Turn the camera off, remove the lens, gently blow on the contacts (gold dots/dashes) on the lens. Or you can wipe the contacts with a cloth lightly dampened (not wet) with rubbing alcohol.
  2. Reinsert the lens, turn the camera on.
  3. Still the same error?
  4. Open the battery compartment and remove the battery (while the camera is on.)
  5. Wait a few minutes and reinsert the battery.
  6. Still the same error - ship it off to Canon for service.

I was shooting today and all of a sudden I got an error code 01, which says that the lens and camera aren't communicating and that I need to clean the lens contacts.

Wobbly lens I have just purchased a Sony W130. It is my first ever camera. When the camera is off the lens section can be moved about 1/2mm with gentle movement of the camera. When zoom is fully extended it can be moved side to side by gentle pushing about 1 1/2mm. Is this normal or is the camera faulty? It doesn't seem to be affecting the pictures but everytime I use it I get a vibration warning on the screen.


Half mm or so movement is normal in fully extended lens. If camera is not giving any error display during function then every thing is just fine in it. ... Sony Cyber-shot DSC-W130 Digital Camera

My camera 'Samsung ST61' is a new camera, I got it about 2 months ago now, and it has been working perfectly fine, although when i previously charged it about a day ago and turned it on the camera lens came on like normal and the shutter went out but it beeped about 2 times and shuts off again to its normal state. I am really confused to why it may be doing this, but when I took it to a shop today they said it may be faulty as the lens is a little bent when it goes out? What am I supposed to do

I have a Canon 40D and tried to use my Sigma 28-300 1:3.5-6.3 DL Hyperzoom lens on it but the camera kept telling me that it could not communicate with the lens and that I should clean the lens contacts. I cleaned the contacts several times (which were not dirty) but still got the same results. The lens is 5 or so years old, is it possible that the lens is not compatible with the 40D?


It could be that the lens, being so old, needs a firmware update. Go to http://www.sigmaphoto.com/service-support for a service form and instructions. ... Digital Cameras

I have a Canon Rebel Xt that occasionally has problems with the shutter button suddenly not working. The camera is still on and all the menu buttons continue to work. It acts like the lens decides to quit communicating with the camera body. The only fix I have found is to take the battery out for 10-15 sec. and it works like normal. Any advise on whats going on would be great, Thanks Brandon
