Lens Squeak - 24-70 2.8 USM II - Is this Normal?

[Sabaki]

There was a similar post to this about 3 months back.
Turns out there was a faulty batch of 24-70's made in late 2012 that had this issue. If I remember correctly and I may be wrong, the squeak was a a result of those electronic ribbons being housed incorrectly. I was also of opinion that those ribbons would wear out quickly due to the constant rubbing.

I say fight my friend. You cannot spend $2000 on a defective item only to be turned away by manufacturers who refuse to do the right thing.

Consumer protection or a civil case. I would.

I opened my box to check for the production series number, batch number, can't find anything that states those numbers. Maybe it's different in Europe. Mine is a 2012 edition with the old style lens cap, I had it swapped due to the ticking sound, this one however works perfect. I wonder if there are only the early ones that work and all the latest comes now with both squeak and tick.

It's epic fail from Canon not to address the issue and replace yours and other peoples lenses directly , instead of keep wearing people out by 5-6 replacements through their dealers, it's sickening....

The '032' etc numbers people are talking about the beginning of the serial number. It's on the lens itself, the warranty card, and printed on the box (the last set of digits under the bar code - meaning it's often of the vendor invoice, too.

Mine is (951) meaning Oct 2012, came with the old side-pinch cap, and is optically and mechanically perfect.

Thanks! Mine is "940" making it a September 2012, if I read it right. A classic ! ;D

Update. Spoke with Canon on 1/7/14. Per the engineers - 'the noise did not occur under normal operating circumstances nor was the squeak able to be recorded on any audio equipment.' Lens will be shipped back with a smile from VA.

My last recourse would be to record some audio of the squeak on my 5D3 and send it back in yet again - but for what? This would be its 5th trip in if I'm remembering correctly!

I give up - Canon has wore me down. Tired of the constant back and forth and being down a lens. I'll just take a hit and sell old squeaky…It almost lasted a year haha! Im seeing Zeiss in my future. Very dissatisfied with all things Canon, but looking forward to the great things I've been hearing about Zeiss.

I miss manual focus primes... I know they won't squeak

Thanks for following my story friends and I hope you have better luck than I!

Man, that is some pretty $h1tty treatment of a customer! So sorry to hear that...

I can absolutely recommend the Zeiss 50 f2 mp, wonderful lens that can do it all.
