k-x focus speed with 18-55m

I cant help but notice how slow the af is on this lens? I wait sometime 5+ seconds when holding down the shutter waiting for my dslr to finish autofocus and take the picture. Is this normal with this kit lens? Thanks

I have the 18-55 AL II lens and the focus is quick and right on. Are you focusing in daylight? Low light? It can hunt a bit if there is not much light.

It happened during overcast skies and occasionally indoors. I guess it could be due to the poor lighting condition. I guess I cant expect it to focus like point and shoot cameras. I only say this because sometimes I may ask passerbyers to phoograph my gf and I.

Mine does it in low light conditions, but in sunlight, it's quick to focus.

I have the Kx with 18-55 also and while I do think the AF is slow, I have never waited 5sec. In low-light it will take maybe 2sec or if it is too dark it will not find focus at all.

I have noticed though that some lenses will AF faster than others. I have a Tamron 28-105 that focuses much faster than the kit and when I had a 18-200, that thing was really slow in lowlight.
