Nikon 24-70 focusing noise

  1. Hi,
    After a long wait I finally received my Nikon 24-70/2.8 however I noticed that while focusing it makes a crackling sound. The sound is not very loud but it almost seems like a lens with VR trying to stabilize. My 18-200 sounds much quieter than 24-70. Did I get a bad copy of the lens? Anyone else experience this?
    Thank you for your response.
  2. Does it continue making the noise when AF has locked or is it just when racking?
  3. I tried a few of my own AF-S lenses before responding and none of them make that much sound when focusing.
    Nice job posting that video so that any responders can hear exactly what you're talking about. So many times it's a lot of guesswork trying to figure out what people are trying to describe.
  4. No, the noise does not continue once the focus has been locked. Its almost like I hear few knocking and then it locks the focus. However this does not happen every single time.
  5. My 24-70 sounds exactly the same. There seems to be nothing wrong with that...
  6. Surya,
    Your lens is absolutely fine, the ultrasonic motor in 24-70 is way juicer than the one in a cheap lens like 18-200, it has to move those huge elements rapidly so it needs high torque. As long as it snaps into focus rapidly and there is no cracking/rattling sound after focus has locked your lens is fine.
  7. Arash, I did more test today and one thing that I noticed is that it does not not always focus fast. I compared with my 50mm/1.8 and 50mm always focused fast but 24-70 at times made the crackling sound and at the end of may be 4-5 crackle it was able to focus. Just to let you know I always tried to focus on a spot where there was enough contrast to allow easy focus. None of my local camera shop has this lens; I wish I could compare it with another copy of it.
  8. My 24-70 does that sound in AF-C mode when it is constantly refocusing. Seems normal to me.
  9. Hi there!

    I have the same "issue", mine has the same sound so I suppose thre's nothing wrong with it.....other ideas?
