Question: Work with D7000 ?
Document: This is a good unit. I do wish that it had a little finer manual focus, and it doesn't work very well with 1.4 Ramron multiplier. All in all, I like this lens.
This may infer GRAY MARKET LENS. At the price and complexity of todays cameras and lenses Gray Market purchases will leave you hurting for warranty work, adjustments or out right damage repairs.Again, BUYER BEWARE!
This lens does not have the internal focus motor so it will not work on cameras that do not support this such as the D5000.The pictures I have got are very sharp up to about 400mm. The image quality suffers a little from there to 500mm. It is something I can live with and the images are still usable but get a little soft. Up to 400mm this lens is very sharp.
We purchased this item to use with our Nikon D5000. Unfortunately it doesn't work with our camera body. From the manufacturerUnfortunately the 200-500 lens is not compatible with the D5000, becausethe D5000 does not have an auto focus motor in the body. The 200-500 alsodoes not have a motor, so there is no auto focus capability between them.The tamron site has more infoAmazon graciously accepted the return.
Tamron has just about the worst customer service I have ever dealt with. They want to charge $225 dollars to clean a lens which they claim is causing the issue. However, they do not want to stand behind their work and warranty the service. So basically the want to charge $225 and I have to hope they repair the lens or else I'm out of $225. I'm done with Tamron.
I have had this lens for almost a year and normally don't write reviews but the person who gave it four stars claims the pictures were great and focus fast and everyone agreed but gave it four stars? The lens deserves five stars for the price and flexibility. It does seem to work better on my 20d then on my 1Ds, the pictures are sharp and focus is fast for a zoom lens.
I bought this lens about 2 weeks ago. I was shooting with Nikon D40x for a few years now and have a 18-200 lens with it.I bought this lens because it had the best price for a decent lens. I also bought a D90 camera for it because the auto focus of this lens will not work on any Nikon cameras (D40,D40x,D60 ...) that needs the auto focus motor inside the lens.
Just started in dslr one yr ago-nikon d60 + sony alpha. both camera with 200mm lens. lots of nature photos and was considering a longer lens. saw the reveiw for the tamron 500 and decided to go for a try.tamron is decent but heavy. AF does not work with nikon d40 or 60! MF is ok.  tried it on a d50 without problems. tried a 75-300 and really like it.bottom line-suggest 300mm lens.
I gave this lens a try as a cheaper alternative to the Canon 100-400 L IS lens. After one outing, I returned the Tamron immediately and bought the Canon 100-400mm L IS lens.This lens is pretty soft at anything above 400mm, and anything below f/8. If you do any kind of print work or like to do heavy cropping the softness of this lens will really bother you - there's no way you can use a 1:1 crop.
Lets start this review by stating the obvious, this is not a 500mm prime lens costing about 10K, this is a decent lens with great range for under 1K. It is silly to start comparing this lens to others that cost 6 to 10 times as much money.I am using this lens on a Nikon D7000. I have read other reviews about the slow focus speed but I am not seeing that on my camera body. It focuses fast and adjusts rapidly using the continous mode.
Answer: Yes.  It works well with a D7000.  It then has an effective focal length of 300-750.  I find it works best with autofocus on a full frame body, like a D600 or D800.  With a D7000, I manual focus to get it close, then switch to auto.  If you try to go full auto to find the initial focus, it can get into a search loop.  With full frame, that's less of an issue.
