A lot of 75-150 have a separated element near the center of the lens. If
your lens has it (degree of separation can vary) it will make the lens very
difficult to focus. Or you will notice that you simply can't get a sharp
image.
You can sometimes see the separation, by holding the lens up to a light,
looking through, and trying to focus into the center of the lens with your
eye. If separated, you'll see something like a hair running through a lens
or what a
looks like a large bubble covering the majority of the diameter of the lens.
I check every 75-150 for it as it will change the repair price.

Hi Robert,
I'll be getting this zoom delivered shortly. Just
asking: Was there a problem you found with your lens
that you send it to John for service or did John
discover that "bad" element during a routine CLA?
So I'm wondering if I should have my lens checked
outright for that defect before I start to use it in
earnest.
Thanks,
Thomas
