I've just bought a second hand XF 90mm. It's in a perfect exterior aspect.
It function apparently well, with an efficient AF, a perfect focusing symmetry ...
But when I tilt it longitudinally (front lens up-down), I can ear a light "clock " (or "click" ?), as if lenses are moving inside.
I know an equivalent noise in an IS lens, but the 90mm has no stabilisation system inside.
Is it the same with a new lens? Thanks
