I've bought my eos 450D just yesterday. And today suddenly I can't take photos beecause it needs cleaning lenses' contacts(error 01). I tried to clean them but nothing changed.. What should I do. Thnks for your help.

Seems a lot of people are having the same problem. Take the lens off the camera and clean the little gold contacts (metal squares) on both the lens and the body with isopropyl alcohol or pre-moistened len wipes.

Rob, Error 99 is Canon's catch all error code, yes my first impression would also have been to clean the contacts but something else that is happening is the camera firmware may need to be updated to handle that particular lens. Camera updates are free on the Canon site and actually can solve a lot of hidden processing problems.

That lens isn't really suitable for your 450d as it's an APS-C sensor size with a 1.6 crop focal factor which will give you more like a 24mm focal length.

You may also want to format the memory card and clean your battery terminals both the battery and the contacts in the battery compartment.

Best little cleaning item for cleaning contacts is a pencil eraser (new) lens contacts or battery something about the soft rubber cleaning off the most suborn dirt and electrolysis.

Don't use a "used" eraser obviously it will transfer the dirt to the contacts over removing what you want.

Hope these techniques work they have for me

Clean the contacts where the lens and camera body meet with a cotton swab lightly dampened with rubbing alcohol.

Error 01 means that communication between camera and lens is faulty. Try to clean lens contacts.

This is what the people at the canon tech support say to do for error 99



read this!! :)

The guy at tech support listened and then told me that the lens contacts were dirty and to get a pencil with an eraser on the end, just a regular old pencil with a red rubber eraser. Detach the lens from the camera, hold it so that the lens’ gold contacts are pointing down and lightly erase their exposed surface, cleaning them of any hand oil that might have gotten on them.

Do the same thing with the gold contacts inside the camera body. This is a bit harder but it’s doable: just hold camera so lens opening points down so no gunk falls in. Erase lightly. I used a lens cloth and dabbed at the contacts rather than blow them so as not to blow the erasings inside the camera.

I did this to each of my three lenses just to be sure. Lo and behold, it worked



hope this works for you!!!! have a nice day!! :) :)

It is asking you to clean the electronic points on the lens that come into contact with the camera body when the two are fitted together, in order to power the lens functions.

If other lens work ok, try giving the lens electronic contact point on the mounting plate a light rub with a dry cotton-bud, may be a fingerprint .

shutter struck, if the battery has no enough charge the shutter motor will not rotate fully,charge the battery and try.

Try cleaning the contacts on the lens. Use a clean pencil eraser and hold the lens upside down so that the eraser debris falls onto the table and not into the lens. If this doesn't fix the problem then you need to have the lens repaired.

If the lens is a super it may need a rechip

it may not be compatable with digtal camers to test set camera to AV get a iris of F22 using the stopdpwn button see if it stops down if yes it is compatable but faulty if nothing it not compat and need rechiping
