David,
Here is the link to Thom Hogan's review.
http://www.bythom.com/70300lens.htm I have had this lens for about 5 years now and Thom's review echos my experience.
It is my favorite walkaround lens on my D70, even street photography. I have also used it on a D200 with good results as well as my FM and N70 film cameras.
The lens is best shot at f8 or f11 but wide open on the short end up to about 120 makes a good informal portrait lens.
If someone is looking for a light, compact lens for hand carrying with decent quality this is one I would recommend. Especially if they are on a budget as they can be found in the $150 to $200
range. The one complaint I have is it tends to hunt for focus in low light and low contrast situations.
