Canon 180mm Focus Squeaking
« on: October 06, 2012, 06:35:37 PM »
I just received a Canon 180mm f/3.5L USM from Amazon, and I'm very impressed with the lens except that I noticed one thing that has me somewhat concerned: I can hear a faint squeaking from the focusing mechanism when it is moving, particularly on AI servo, probably because it's moving so much. It's not very loud or offensive, so my first thought was that perhaps it's normal for this lens since it is of an older design. However I've never heard such a noise from any other USM lens I've owned, so I thought I'd ask the 180mm macro lens owners on the forum, see if anyone else noticed this squeaking. If not, I still have plenty of time to exchange it with Amazon.

Return it if you can't compare it with another lens.  If the replacement does the same thing, you might just have very good hearing.  Its unlikely that the replacement will have the issue.

+1 Agree.  Have had 180mm Macro for couple of years, not fast focus, but definitely not squeaky.  Probably a copy issue.
