I presume you mean the Quantaray 70-210 f/4-5.6 model. I haven't used
the lense, but from what I've read online about Quantaray, they're one
of the worst brands available. The price should be your first clue to
quality.

And no offense, but why would you want to put a crappy lense on such a
nice camera? The lense does all the work in forming an image for the
camera to capture, so it's arguably the most important part of a
camera system.

I think you've put the cart before the horse.  The LENS is the first link in
the image chain, and your image can be only as good as your lens.

Quanterray lenses are Ritz Cameras' house brand, and I believe that they are
manufactured by the lowest bidder.  Last I heard, they were being made by
some Korean outfit.

Ritz would typically put Quanterray lenses on name-brand cameras and
advertise the kits for sale at prices that appeared to be beneath that of
the competition.  Their typical consumer thought he was getting a good deal,
not realizing that he was comparing the price to that of a camera with an
OEM brand lens.  Most consumers don't understand the subtleties of these
things, so Ritz exploited their customers' lack of knowledge.

And you ask about Quanterray lenses?  I'd use them for doorstops.

I have had my flings with cheap lenses and I have always been disappointed.

Nikon makes a great 80~200 AF f2.8.  That's what you should be putting on
your D200.  Lots of used ones floating around. (This is assuming the other
posters are correct in that you are actually looking for an 80~200.)

Ok you found out what folks think of Quantaray lenses. The best 70-200
for the D200 is the 80-200 f2.8 used (get the 2 ring zoom and focus not
the push pull) they run $500-$1000 used (www.keh.com for a good used
source). For a lens that is a lighter look at the Nikon 70-210 f4 (not
the f4-5.6) it is only available used. For new lenses look at the
55-200, plastic lens but, inexpensive and has  some good reviews, or
the new 70-300 VR lens, which is new and the few reviews of it have
been very good, it is a consumer level lens, not pro.

Good luck
