My K3 is in service for backfocus issues. Kinda disappointed mine had this issue. I'm keen to see if the service department will blame it on the lens, the body, or me.

I spoke to a tech recently and he somewhat indicated that I wasn't testing my focus properly. We'll hello! If I focus on something (like batteries lined up at 45 degree angle) and get a focus indicator on the middle, if I take a shot (even with a tripod and on timer) why is it back focusing?

You are probably doing it correctly.

Please understand though that the focus area is much larger than the red focus indicator. So, check that it is not actually locking focus at the battery beside it.

Hi Roland,
Yes the batteries are apart enough so the focus point doesn't accidentally pick up the wrong battery. Plus I have a white background to eliminate accidentally confusing the camera.

The battery focus test seems to have fallen out of favor. The current favorite test is the vertical surface plus angled ruler. It could be I don't know all the reasons the battery test is generally considered to be a poor test, but it seems perfectly fine to me if the operator ensures the camera cannot focus on anything but the target battery and you have done that.
