One stop further: The next-generation Vibration Reduction system incorporated in this lens allows for up to 5-stop compensation, enabling photographers to shoot at shutter speeds five stops slower than would otherwise be possible. A significant upgrade, the increased stability greatly minimises the effects of camera shake and extends opportunities for low-light shooting.Superb resolution and image quality: Despite its lightweight build, this lens doesn't cut any corners when it comes to performance. Crafted to deliver outstanding resolution and contrast in diverse conditions, the optical construction boasts 20 elements in 14 groups, and Nikon's Nano Crystal Coat is employed to combat flare and ghosting.Highly Versatile: Well-balanced in terms of size, weight, price and image quality, this lens also has a dedicated tripod collar ring, the RT-1. This optional accessory helps to improve tripod balance and allows quick, smooth transition between vertical and horizontal orientation when shooting in either portrait or landscape format.Hiro Sebata, Product Manager for professional products at Nikon UK says: "This new NIKKOR f/4 lens offers high quality performance and flexibility, ideal for enthusiast and professional photographers looking for a versatile, portable tele-photo lens, with the added benefit of the enhanced Vibration Reduction system."
