it will not autofocus on the d3200. I had one but sold it recently. This is in my opinion a classic case where Mr Rock... has made such a positive review of a lens and now everyone wants one.
The reason I sold mine was the following:
- its heavy
- its a sliding zoom. When zooming air will be sucked in and out of the body increasing the chances of dust ingress.
- it has no vibration reduction/optical stabi/vibe control, not so much an issue at the short end but can certainly be missed at the longer focal range, especially in low light conditions.
That being said, the lens is really very sharp and focused amazingly fast on my D7000.
Here in europe you are looking at an average of about 120 euros for this lens in good condition, IMHO better off buying the nikkor 55-200 which will autofocus on your camera and has vibration reduction........... is currently to be had for 110 euros!
