Tamron SP 70-300mm f/4-5.6 Di VC USD Telephoto Zoom Lens for Nikon
Telephoto zooms can be quite pricey, but this Tamron extends from 70 to 300mm and is still priced under $500. The vibration compensation is a must for any telephoto and allows for shooting at up to four stops slower than lenses without it. The ultrasonic autofocus motor should be both fairly quick and quiet. Constructed with low dispersion and extra low dispersion elements, it has been developed for excellent digital images. A more expensive lens will get you a better minimum aperture, but this Tamron is an excellent option for the price point.
