Fuji 18mm Aperture ring feels "sticky" compared to 35mm?


Wondering if this is common and if so, no big deal. I just took delivery of my Fuji 18mm, popped it on the xpro and gave the aperture ring a spin. Compared to the 35mm, the ring feels sticky or tight as if there's more resistance than the 35mm. The 35 feels much more fluid and smooth.
Are the rest of you with this lens combo feeling the same thing? If not, I may be giving Fuji a call tomorrow.
Thanks for any info, Kris
