I received a new piece of kit today – the Nikon TC-20E III 2x Teleconverter!. I will never be able to (or want to) afford a 400mm+ lens so I figured this would be a great compromise. With a 1.5x crop factor on my D7000, this 2x teleconverter will give my 70-200mm f/2.8 lens a focal range of 210-600mm with a maximum aperture of f/5.6! Hey, not bad! Maximum sharpness will probably be achieved at f/8, so with some decent light, VR technology, and some support, I should be able to manage some good distance shots. Birding anyone?
