K-3 back/front focus lens adjustment

No matter how I try to change the Fine Adjustment on K-3, it never makes any difference in the actual focus of the lens itself, seem like a bug to me.

How are you testing it? It's fine focus, so if you adjust 10 or 20 micrometers, it may not really be too noticeable.

I know it works on mine. I tested it by throwing one lens to -100 and +100 micrometers and they definitely shifted the focus region.
