Hello. I have a Nikon D3000 with a Nikkor AF-S Nikkor 18 - 200mm 3.5 - 5.6 GII ED lense. I would like purchase a 2 x tele converter. Can anyone please recommend to me the correct one to buy for this lens. This is my first DLSR camera so I am new to this. Thank you.
Welcome to Nikonians! I would not recommend using a TC with the 18-200mm or any slow wide angle to telephoto zoom. The 18-200mm was never designed to be used with a TC and none of the Nikkor TC's will even mount on it. With a 2X TC you will loose two full stops of light giving you a 36-400mm f/7.2-11 so you will loose Autofocus. That combined with the penta mirror viewfinder in your D3000, will cause the viewfinder to be extremely dark even in the best ambiant lighting which will make it very difficult if not impossible to focus manually. In addition the IQ (Image Quality)with a 2X TC will be extremely poor. Good Luck and Enjoy your Nikons!
Thank you for your reply. Would you recommend I purchase a seperate zoom lens with more capability? I have been enjoying wildlife photography but would like to get better and more close up images. I have found using the lens I have on the max 200mm I am getting slightly hazy images. Thank you again.
The 18-200VR is at its weakest at 200mm, and especially so wide open. For the things that you seem to be wanting to photograph, a much longer lens is more than a good idea, it's probably close to essential. Something like the Sigma 150-500 HSM OS would be a good option. There are some other options, but they start at around $1000 and go way up from there. The Nikon solutions are expensive, such as the 300/f4 AFS + TC-14EII (about $2000), 300/f2.8 AFS VR-II + TC-20EIII (about $5000) and the 200-400/f4 AFS VR-II (about $7000).

Brian offered some excellent choices, though it ultimately depends on your budget. Another choice is the Nikkor 70-300mm f/4.5-5.6G ED IF AF-S VR (approx.$550.00 US). While it is significantly shorter than the Sigma 150-500mm is is also just over half the price. Good Luck and Enjoy your Nikons!
Thank you very much for the advice. As much as I would love the 70 -500mm zoom I think the size and weight will be too much for me and at this stage is probably a bit more than I need. I will look into the Nikkor 70 - 300mm Many thanks Bev
Contrary to the advice given so far a Kenko Pro 300 1.4 in good light will AF with your 18-200. Results will not be spectacular but at around f11 with good technique it is possible to get good enough quality for a 13 inch wide print. The 70-300 VR will definitely give you better optical performance (13 inch wide print at f6.3) and faster and more reliable AF, especially in low light. Based on UK prices the Kenko is about 40% of the price of the 70-300 VR - and obviously a lot smaller and lighter. Which you decide on is up to you. Digressing the Kenko performs reasonably well with the 70-300 VR.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
