New Tamron lens for Digital
Mar 14, 2005

Brand new Tamron AF 18-200mm f/3.5-6.3 XR Di-II LD Aspherical (IF) MACRO SLR Lens -62mm- f/Canon.

They said:

The new AF 18-200mm F/3.5-6.3 XR Di-II LD Aspherical (IF) MACRO is a high power zoom lens designed for exclusive use with digital SLR cameras using smaller-size imagers and inherits the product concept of the existing AF28-300mm F/3.5-6.3 XR Di zoom lens. Includes Front & Rear Lens Caps, Lens Hood, 6-Year USA Warranty.

By 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 Design

The 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 distribution of optical power throughout the entire zoom range. This design reduces various aberrations to the absolute minimum and achieves remarkable downsizing at the same time. In addition, three hybrid aspherical lens elements and two LD (Low Dispersion) glass elements are used to accomplish effective compensation of on-axis and lateral chromatic aberrations, a critical factor to enhance the optical quality in digital photography. As a result, the lens provides outstanding optical quality in a multi-purpose zoom lens.

  • Lens Construction: 15 elements / 13 groups
