The normal AF uses a special AF sensor on the underside of the camera in the lightbox, liveview AF uses the actual image from the sensor and change the image to get the highest contrast.
So 2 completely different systems and ways are used.

You can calibrate the AF for 10 lenses or so with the K5.

But the 18-135 is not known for his sharpness.
Throw on a prime lens and be amazed, the sensor between the D7000 and K5 are the same so no difference in details there.
