will be used for travel i also purchased the nikon 50mm f1 pro glassIt's an OK lens in my opinion.
For a light, compact, travel zoom with a wide range you can't really do much better.
But the trade off for all that reach while remaining compact is a slow maximum aperature, only OK build quality, and only OK optics.
Don't get me wrong, it's still the best lens in it's class, but in terms of IQ it's no where near the IQ of the nicer Nikkor glass.
So are you planning on using it for fun photos of kids, pets, and while traveling? If so, it will be fine for that, long as you're not expecting edge-to-edge sharpness and can deal with the CA at the wider angles.
If you're expecting "pro quality" results from this lens, you'll probably be disapointed, and would be better off buying a higher quality lens of a more modest range for the same $700.
any reviews for this lens, any personal reviews,someone who has tried this lens?? ..thx mike
In my area there is an annual photography contest where both amateurs and pros enter. Whoever wins gets $5,000 cash. The winner this past year was an amateur using a D200 with a 18-200 attached. He beat out pro's and a lot of serious amateurs. Not bad for a jack of all trades and master of none lens.
BTW the photo (13th green of the golf course--he took it as the sun was going down) was awesome. He sold it to the Augusta National Golf Course (Home of the Masters golf tournament--don't know how much he got for it) and they framed and hung it outside their main dining hall. Pretty impressive.
Cool story!
Is there a link to the photo anywhere?
I agree with pretty much everything everyone has said so far, the one thing I would like to add, is if you are going to use this lens fro portraits, candids or weddings, I would advise to use a flash.
I use a flash with this lens nearly 100% of the time. It just about solves the shaprness problem. The SB600 is just barely powerful enough at f/5.6 from about 20 feet with a Fong dome at 800 ISO.
But I would try to shoot at 100 ISO or less with this lens as often as possible.
I bought this lens a year or so ago and then got the 16-85VR. The 18-200 is now on Ebay. Unless you need the 200mm (a post above is right, 200mm f5.6 is quite useless except at high noon), get the 16-85vr as it's sharper with better contrast on the D300. Although I have a d700 with 24-70 2.8, my main travel pack consists of the D300 with 16-85mm as it's much sharper than Nikon's full frame equivalent 24-120VR on the D700. Nikon really needs a competitor to Canon's 24-105L
One other thing, the 18-200 200mm is not truly 200 unless you're focusing on something further away. As compared to my 70-200VR, the 200mm on the 18-200 at closer distances is more like 135mm. I think it has to do with the lens' design.
