Manufacturer’s Description

The new AF18-200mm F/3.5-6.3 XR Di-II LD Aspherical (IF) MACRO is a high power zoom lens for exclusive use with digital (APS-C size) SLR cameras that inherits the product concept of the existing AF28-300mm F/3.5-6.3 XR zoom lens. Even two years after its introduction, the current AF28-300mm is still a much loved and highly evaluated by photographers around the world as a representative model of high power zoom lenses. With the market influx of digital SLR cameras in recent years, the use of high power zoom lenses has become increasingly popular since high power zooms provide the convenience of handling many photographic scenes and the capability of shooting ultra telephoto shots without changing lenses. The popularity of this focal length led Tamron to initiate the development of new zoom lenses to further meet the needs of digital SLR photographers. The result is the successful development of a new zoom lens exclusively for use on digital SLR cameras. The wide to ultra tele focal range of this lens will allow digital SLR camera owners to enjoy digital photography with comfort and convenience. Dedicated for Digital SLR CamerasBy incorporating an optical design for exclusive use with digital (APS-C) SLR cameras, this high power zoom lens provides the focal length equivalent to Tamron's 28-300mm (when converted to a 35mm format). Therefore, you can meet almost all photographic opportunities with this single zoom lens without changing lenses. When paired with the SP AF11-18mm zoom lens, simultaneously introduced by Tamron at Photokina, you can enjoy thoroughly digital SLR photography with the combined focal length coverage of 17-300mm.Optical System Uses Special Glass and is Optimized for Digital SLR Characteristics in order to Enhance Optical Quality in a Compact DesignThe new AF18-200mm high power zoom lens from Tamron features an entirely new optical design using XR (Extra Refractive Index) glass in an innovative way in order to optimize the overall distributio...
