EF 35mm f/2 IS USM AF sound

[Maximilian]

Hi there to all, especially the 35 f/2 IS USM owners!

I finally made the decision to get that lens giving me some more WA aperture to play with.
And while having a cash back promotion here in Germany now I got it.

Today it arrived and something about the AF sound is confusing me a little bit.
Although being ring USM it seems a little bit loud for that and also the focusing ring seems to be a little bit tight.
It also sounds a little bit rough and scratchy.
In comparison my 24-105L is more quiet ans smooth. And the 85/1.8 is at the same noise level but sounding smoother.
Maybe it's just normal or something that will change while it will wear in mechanically.
Everything else (mechnics, IQ) looks okay.

So my question to you:
What experience do you have with the AF sound of that lens?


Maybe I am just a little bit spoiled from the L quality or my ears are just too good
Thanks for your replies.

Disclaimer: I have no chance during the next days to go to a store to compare it to a second copy. Otherwise I would have done this first.

Hello Max, I've had mine for about three years, focus ring is smooth and quiet as is the USM AF, from memory it's always been like this even when I first got it, I also have the 50L and 85L they feel and sound about the same. I also use the lens quite a bit in manual focus with a Sony A7 and focus is smooth and quiet in fact the loudest sound is the IS which is barely noticeable, hope this helps.

it should be quiet.. if it sounds closer to the 50 1.8 II then say the 35 1.4L, you have a problem

I bought one of these ,refurbed by the Canon website, and the AF is loud enough that I noticed it. Seems to work OK. Supposedly it was vetted by a Canon techs so ....

Thank you very much for your replies nda, TeT and gmb!

To make it short: lens seems to be within normal specs.

To make it long:
I couldn't compare them to the lenses mentioned by you.
I took my time to get to a store and compared it to another copy.
AF sound was quite similar, focusing ring felt the same.

Thank you for your help. Case dismissed.
