Nikon Telephoto AF DC Nikkor 105mm f/2.0D Autofocus Lens
Most enthusiasts can't afford to spend five grand on a telephoto lens that's also fast. Nikon's Telephoto AF DC Nikkor 105mm lens is a good alternative, for about a fifth of the cost. This lens only has about half the zoom of the 200mm option, but the shorter focal range means vibration reduction isn't as essential, which makes this model significantly more budget friendly. While the lens doesn't include vibration reduction, it does include a defocus control, which allows for a wider range of results when looking for a bokeh effect. The lens also weighs less than 1.5 pounds, which makes it a nice option for traveling light.
