Decent lens, but there's 2 versions it looks like.
4 December 2013
Summary: The lens offered appears to have changed alittle. When I bought it back on 3/13 there was no autofocus motor in the lens and was listed as model number A15. Now a new picture appears clearly showing an autofocus motor and the model listed as (A15N). Amazon should probably update the listing description as it still leads the customer to believe there is no autofocus motor. All in all it's a decent cheap lens that will give you alittle more reach than the basic kit lens.
Summary: Excellent image quality, easy to use. Price is so low from KEH you will be immune from buyer's remorse. With Nikon mount, this lens requires camera with focus motor screw drive in mount for auto focus. Manual focus works on all cameras.
Summary: A friend recommended this brand of lens for my Nikon after she purchased one through National Camera at their recommendation. I am glad I took her advice. This lens is far less expensive than the Nikon brand lens and works just as good. I do have to get used to manually focusing the shot once I reach my desired zoom range. But overall I am pleased with the lens.
Good product for the price especially for somone starting out on a budget

Summary: Contrary to what several others reviewed, this is an autofocus lens if you've go the camera that will do it. Running on a Nikon D800, it works fine, a little noisy, but you get what you pay for. On my 3100 its strictly a manual focus lens. Few test shots I've done so far seem fine, but won't know more until I can really get out and use it this weekend.
Summary: good build for themoney and will be used as a quick back up for my Nikon. As was stated in the ad the auto is not compatible with the d5000 but tried it on my brothers d300 and its auto focus was dead on.
Summary: I bought this on sale here for 40 smackers. The quality and feel of the lens is ok, it takes great shots tho. Some complain about the focus noise, its true it is loud and if you don't have a body with a focus motor then you don't have to worry about it :). I have recommended this to others who want a cheap lens that works well and they seem satisfied with it.
Summary: For the price of $40, why not? This lens fits my Nikon d90 well. Comparing this lens to the 18-105 mm Nikkor lens, this lens is actually smaller. I use it as a zoom lens. The only draw back to this lens is putting it on the d90 body. It's backwards. Whenever I change my lens, I forget that I have to spin it backwards to snap it in. It's not a big deal but I get what I paid for.
