A:AnswerI actually own a D600 and D5200. They should work perfectly together. Make sure you have VR on since it's hard to keep stable if you are all the way out in the range.
A:AnswerI personally own this lens and it's worth it. You won't be disappointed. I wouldn't go any lower than this lens though. Better glass when you can spend more.
A:AnswerA wide angle lens is recommended for landscape photography.
For a youth football game you need a telephoto. Your 70-200 is a telephoto lens. To get closer facial expressions you need to consider how close you can get to the field too. 200mm is not bad but anything over 300mm is better. If you can afford a prime 300mm or 400mm with a low F by all means go for. Other wise you can get good results with a 70-300mm
A:AnswerThe d3000 requires a lens that has a built in AF-S motor. The Nikon 70-300 VR lens has a motor built in it, so it will work for your camera. The 70-300 VR is a pretty large and heavy lens so unless you really need the reach to 300mm you may what to opt for the Nikon 55-200mm VR lens.
A:AnswerIt might work, but your aperature on the lens would be like F8 and your camera might have difficulty focusing. You might have to manually focus.
A:AnswerIt depends on which body you want to use it on. In many cases just set the f stop to f22 or smallest ap and it will work. I believe there are compatibility charts available online. Some older lens will not work on Nikons that require special lens, generally these are the lower cost models.
A:AnswerThis is a US product, not grey market. They only say 1 year since you must registered within 10 days of purchase to get the additional 4 years of extended service coverage. So it's really 1+(optional 4).
A:AnswerThe only option that is reasonably priced is the Nikon 55-300mm VR lens. Nikon does make an 80-400 lens that is much larger and cost about 4 times as much. Both have built in AF-S motors and will work with your camera.
A:AnswerLook into a faster lens, say 2.8 if you can find one for that model. I know there are plenty of them for the D7000 but remember that is a large investment.
A:AnswerThe Nikon D5000 is supposed to accept and autofocus all AF-S lens. Rather than believing a stranger on the internet, you should take your camera in and ask to try the lens before you buy it, to make sure that it works and does what you expect it to.
A:AnswerIf you are already using the 70-300mm Nikkor on your 3100 you might also look at adding the Nikkor 2X teleconverter to the lens. Your Best Buy store should be able to order that lens for you and they are available online. They are a bit pricey but the results are fantastic.
