You shouldn't expect A/F miracles from a 5 year old design pancake lens. I did an informal test once between this lens and the Olympus 45mm, which is acknowledged to be quite fast. I tried this with a range of light levels. The difference in AFS, provided no hunting was induced, was barely noticeable.

I noticed the difference. I had read that the AF was slower than newer lenses,  it also misleading comments like yours saying that there is no noticeable difference in AF speed in real world use (there is).

It does however take a long time to move focus from close to far away or vice versa. If you read the little manual you will see that it is not intended for AFC and in fact does not work in that mode. Hence it is unsuitable for video work using auto focus

I wasn't trying to use it for AFC or video.

If you use it as intended it is a very sharp and versatile lens

Sharp maybe, but a lens that can only handle static subjects is not versatile.
