What should I get for my telephoto Nikon D2x?
Now I have a nikkor 55-200 mm lens for my Nikon D2x, and I really love, but absolutely This summer I am going to do a safari in Africa and I worry that it will not be able to get close enough to get some really up close-ups of animals. In other words, I want to upgrade, but I need something preferably under $ 1,000. Any ideas?
After 200 mm, things get very expensive. The objective the journey is really the 200-400 mm f / 4, but it costs about 5 times its budget. So you may want to look at the 70-300 mm VR lens as a compromise, but well within of its budget from $ 1,000 Make sure you get your new objective in plenty of time to "road test" it for a few months before attempting to use in the "wild"
