Title: GF 110mm Lens - Is this an issue?
Post by: Mike Guilbault on December 07, 2025, 12:15:55 am

I just picked up the FUJINON GF 110mm f/2 lens. If I tilt/rotate the lens back and forth, it feels like the elements inside are sliding back and forth. Is this normal? Never felt this in other lenses.

Mine does the same thing. I haven't noticed a problem with the IQ. Although now it worries me....

It’s normal.  There is a floating element in there that activates when powered up.  Part of the linear motor focusing.
I’d not make a habit of shaking it like Maracas, but normal movement is not an issue.
