This is Nikon’s new standard lens for shooting surfing from shore. It adds Vibration Reduction (VR) to the previous 600mm f/4 AF-S II lens.
VR doesn’t mean much for sports except if slow pans are your thing, but VR is crucial for wildlife photographers who are always working without enough light, or working with teleconverters. (No, I’ve not tried it with VR and a teleconverter.)
In addition to VR, another reason to drop almost ten Gs on this puppy is that it focuses more closely than the earlier models. This 600mm f/4 VR focuses to 16.4 feet or 5m, and even a little closer in manual focus.
Personally I use 600mm lenses for nature and landscape photography. I’ve always loved how I can crop a tight image from reality. For instance, point a 600mm lens at the reflection of the setting sun in any mirrored office building or at the wet sand at the beach, and your image explodes with light and color.
