Canon 17-85 IS USM Making rattling noise

sfsmmq — Sat, 04 Apr 2020 22:01:27 GMT

Hello everyone!
I bought an old, second-hand, Canon 17-85 IS USM lens, that has been sitting on my shelf until recently. After a serious test, that unfortunately I did not have the opportunity to perform upon buying said lens, I discovered the following issues with it:

- The lens makes a rattling noise, similar to the one of the Autofocus Motor, when I am not focusing at all;
- The camera does not turn itself off when this lens is coupled. Adittionally it makes the same noise every so often;

- Turning off Autofocus and Stabilizer does not solve the sound

Could anyone help me identify the potential problem?
Thank you all in advance!
Regards

Samuel

Greetings,

What body are you using this lens with?

Check the contacts on the lens and body. Make sure they are clean.

There is a procedure to re-align the motor with the lenses ability to focus, but I doubt thats your problem since it rattles and doesn't allow the camera to shut off.

Do other lenses work ok?

If yes, you probably purchased somneone's lemon. I would discontinue use, chalk it up as a leaning experiience and not purchase items you haven't tested before purchase.

Yes, I can. It's broken. More bad news it probably isn't worth fixing but a call to Canon service will answer that.
