haven't really done any direct comparison. Is it MUCH slower?I found this lens auto focusing slower than nikon 18-105mm VR lens(comes with my D90 kit).. Is this common or my some problem with my lens?
y'know.... when you half-press ths shutter release button on a PnS (point-and-shoot compact camera), the darn thing makes some whirring noises and tries its darndest to achieve focus lock....sorry what is PnS speed?
your comparison test has to be a bit more scientific.It is smooth when i switch to manual focus... i think is hunting focusing as I am tryin to shoot my hamster which is running nonstop.. thanks for the informations : )

The 50mm f/1.8D was almost as fast as the 18-70 was on my D200. I don't see how the 18-105 can be any faster than the 18-70 so, maybe it's just your camera's AF motor being slow.
D200 focusing speed is definitely faster than the D90's....
the 50mm 1.8D has no internal AF motor. it depends on the body's AF motor, thats why some older model can only use this lens in MF.
TS is saying his/her 50mm f/1.8D's AF is slow... What has this got to do with MF or not?
I wouldn't say OF COURSE so resoundingly.nothing to do with MF, i said MF in some older model, not his model...
18-105mm has internal motor whereas 50mm dont, so ofcoz its slower in comparison. do you run faster if you move your own legs or someone push you from behind?
