AF 18-200mm F/3.5-6.3 XR Di II LD Aspherical [IF] MACRO
Due to its very big focal length range this 18-200mm is suited as a standard lens for practically all photographic situations. Especially when travelling, its ultra-compact and light construction offers perfect photo fun. From wide-angle to telephoto- you can master many photographic situations with this lens. The18-200mm Di II lens stands in the tradition of the legendary range of Tamron mega zooms and has a 11.1times zoom corresponding to an equivalent of 28-300mm when compared to full frame cameras. The18-200mm Di II works with innovative XR glass (extra Refractive index) to optimize the optical performance in the whole focal length range. This design reduces several aberrations to an absolute minimum and at the same time ensures a more compact construction. Moreover, three aspherical hybrid elements are used to avoid spherical aberration as well as two LD (Low dispersion) glass elements to compensate for chromatic aberration. The result is a versatile zoom lens with outstanding optical quality. It reaches a magnification ratio of 1:3,7 and, hence, is suited also for macro shots, with a minimum focus distance of only 45 cm. Experience the versatility of this lens which sets a new norm in standard lens coupled with a fantastic price performance ratio.
Please note that Di II lenses are made for the exclusive use on digital SLR cameras with image sensors smaller than 24mm x 16mm. Di II lenses cannot be used together with a full format or 35mm SLR camera, as their image sensors are not able to cover the entire area of full format resulting in dark corners of the (i.e. vignetting becomes noticeable).
Please note: The 18-200mm became available with a built-in motor for the Nikon D40, D40X and D60 (Model A14NII) from March 2008. The A14N model which had been available up until March 2008 is only compatible with the D40/D40X/D60 in the MF mode due to the fact it doesn´t have a built-in motor.
