You know, I made the view that the PANA 20mm f1.7 was slow to AF and should be avoided by those that need to take pics of kids and fast moving items / people. This was quite a few threads back.

There are a few that adamantly state my (and many other's experience) is flawed and that the PAN 20mm - both versions are perfectly capable of 'catching' that moment.

Its plain not.

Choose 17mm or 25mm OLY for that.

Choose 20mm f1.7 if you don't NEED fast AF under any circumstances or are perfectly happy to live within its limitations.

It is unfortunate you got misinformed. And yes there are many that are misinforming leading to poor purchase decision.

I do not have photos of kids (I do not have grandchildren, yet), but I have one old photo of the dog. As you know, dogs even more difficult in compare with children.

I think this is a poor example. The dog is stationary - not exactly running towards the camera or anything like that.

We don't know, maybe the dog pushes the table towards photographer and does it really fast.

20mm lens owners probably didn't try photographing at bowling places or anywhere with the light level about ISO1600, F2.0, 1/20s. I did, and 20mm lens is barely usable in such situations.
17mm F1.8 lens, however, locks focus without problems. Here is an example
