Hello everyone, I need your advice on this.
Recently I started to hear clicking/ticking noise coming from my 10 yrs old 24-70 f/2.8 version one. This clicking/ticking noise happens when I zoom from 70 to 50mm. It would happen once every 3-4 times when I zoom from 70-50. I also notice that when I take out my camera after a long period of unuse the clicking/ticking sound would be a lot louder and it happens when I zoom from 50-35mm. After that it would happen once every 3-4 times when zooming from 70-50. I searched online and found that many people who bought the version two in 2013 also experienced the clicking/ticking sound when zooming. The difference is some of the version 2's clicking/ticking sound happens out of the box, mine happens after almost 10 years of using. I have no idea what's happening here, should I send the lens in? The lens is sharp, focus is accurate and zooming is smooth. It's the noise that concerns me. Do you experience this clicking/ticking sound with any of your Canon zoom lens?
Thank you in advance for your answer! Nate
