Hi All,
I recently bought a refurbished EF 70-300mm f/4-5.6 IS USM (non L version), the first copy I got was really load when the IS was on. I sent it back and got a second copy which is much better, but still loader then any of my other lenses. Is this normal for this lens, or for that matter, any lens?
The lens finds focus quickly enough, but then for a second or two after there's a whirling noise followed by a slight "thunk". It only seems to happen when IS is on.
Thanks in advance for your insight.
