Pentax DA 21mm - ring focus not smooth?

i'm testing a Pentax DA 21mm

when i use it in manual focus, for my fingers the focus ring is not always smooth:

see focus symbol meter "m" (not feet "ft"):


between 0.25 - 0.20m is more hard.
it is normal?

No, I would say that is not normal. My DA21 is smooth from one end of the focus range to the other.
