jzucker Offline • • • • Upload & Sell: On p.1 #1 · Does the 70-200L F4L IS lens have a "hitch" in the focusing? Trying to figure out if there is a problem or if this is normal. In the close range of the focusing ring with IS set to 1 and autofocus on, when attempting to fine tune the focus (focusing ring) there seems to be a hitch. It almost feels like the glass is doing a shift. Is that normal for this lens? Dec 13, 2011 at 10:59 PM

My other IS lens does not behave like this but maybe it's due to the lens arrangement? Dec 14, 2011 at 04:03 AM

scalesusa Offline • • • • Upload & Sell: Off p.1 #11 · Does the 70-200L F4L IS lens have a "hitch" in the focusing? I've never felt anything like that with mine either. If its in warranty, get it serviced. It may be a sign of something failing, so its usually better to get a repair done sooner rather than later. Dec 15, 2011 at 06:15 PM
