PENTAX DA* 55mm 1.4 Focus Problem

Hi everyone,

Are there any pentaxian that have the same problem like me?

here is my problem: i use this lens on my pentax k5, when the distance is more than 1 metre, the autofocus works great, it deliver sharp image open wide.
but when the distance is about 1/2 metre, auto focus confirm but it deliver blur image.

my question is : do you have parameter to adjust focus?

many thanks for help

Can you try manually focusing on an object 1/2 meter away?

The closest focusing distance is 45cm/.45m; does it work if you move back just a tiny bit?

It's one nice lens to have and due to the slightly longer focal lenght (55mm compared to 50mm) with the common 45cm closest focusing distance it's actually capable of marginally higher magnification than most other 50'sch lenses.
