DA 55mm f1,4 AF performance on KP

Concerning the critics about the AF-performance of the DA 55 f1.4 like `slow`, `not relalable`, `low keeper rates`, `back- and front-focussing issues` - are these issues as much relevant on the KP or does the AF perform better on this body ?
Thanks for joining your experience/knowledge. Stefan

I selected a few taken with my KP & DA*55 taken this year and placed them into a temporary folder. The ones taken inside our church were mostly in low light conditions, especially where the person is on the stage.
Using the KP's fine tune focus adjustment the *55 was a minus 1. In low light it hunts very little, I am very pleased with it.

"Slow" is probably true. I don't have a KP so I am speculating a little. I tried to take shots from a moving car as a passenger. An ordinary 18-55 gets those shots just fine. The DA*55 doesn't focus quite fast enough. It is just about the only thing it can't do, and you need to be at highway speeds before it's relevant. The slightly slow AF seems to be very accurate, and perfect for portraits or other uses appropriate for a 55/1.4.
