After one year with D7000 and service poitn check-up, still having problems with sharpness!

Hello,

so I owned my D7000 for over a year now. And recently sent to a Nikon service point to do a check-up and all I got is a long report explaining how phase detection AF works!

Previously I always thought it was me who is doing mistakes. Although I wasn't new to photography when I got the D7000 at all! But was new such a DSLR, and only then started using RAW, real manual setting, and a real viewfinder.

After all that time now, I'm still suffering inconsistencies with sharpness.

And in the cases I'm talking about it's obvious the camera focused right, but still the end result and the area/subject in focus is sharp enough.

I considered fine tuning, but haven't did it yet since it's the 16-85 mm lens I primarily use, and the widest aperture is already big! And even photos with F5.6 are suffering from this problem. So it's not probable to be a slight shift in AF!

Here are some examples. I appreciate any input from the more experienced on DPreview.. And any suggestion to to test the camera+lens correctly. I also own the 35mm F1.8 lens at the moment as well.
