both these lenses are Af-S lenses, has anyone had the oppurtunity to use both on the D200 and let us know if the Af speed is relatively the same or noticeably slower on one or the other? dont worry about other factors such as turning the zoom barrel etc, assume one focal lenth has been picked. not loooking for a scientific test chart type of thing here, our local camera store actually has a D200 with a 18-200 kit but i have to justify the extra cash, i used the 24-85 AF-S with flash for closer up indoor basketball under the net shots with film and the F100 and with the now sold D70 and was planning on buying the D200 with or without the 18-70 whichever opportunity presented itself first but now i have this chance. thanks

I have both lenses - with the 18-70 going up for sale shortly - and the 18-200 is better in every respect for me.
Faster, better built, quicker AF and the killer as you might expect is the added bonus of VR. Simply put with the VR and the extra focal length you'll capture shots you could not have with the 18-70 and will get better results into the bargain.
Upwards and onwards.

AFAIK AF speed for AF-S lenses is independent of body.
On my D70 the 18-200mm was at least as fast as the 18-70mm (which I no longer own).
As Anndra (Dubhacan) said, as good as the 18-70mm is for the money; the 18-200mm is an 18-70mm killer.

Ditto. Many of use that had the 18-70 and tried oe bought the 18-200, now have or will be selling the 18-70. Sold mine (18-70) last week--and not for a lot since the supply of used 18-70's is high
