Details: From the Manufacturer

The Tamron AF55-200mm f4-5.6 Di II Macro LD (Model A15) is a tele-zoom lens designed exclusively for digital SLR cameras with smaller-size image sensors at an affordable price. Di (Digitally integrated)-II lenses are designed for exclusive use on digital cameras with smaller-size imagers. This lens is not designed for use with 35mm film cameras or digital SLR cameras with image sensors larger than 24mm x 16mm.
For photographers who bought their digital SLR camera in a kit with a standard zoom lens but are dissatisfied with the telephoto capability of the standard lens, the AF55-200mm f4-5.6 Di II LD Macro offers in a second lens a desirable telephoto range at an affordable price. The tele-zoom from Tamron will allow these photographers to enjoy the telephoto capabilities that yield dynamic images in many photographic situations including sporting events, large wildlife, scenery and portraiture.
Popular-type Tele-zoom for Exclusive Use on Digital SLR Cameras
This is a telephoto zoom for exclusive use on digital SLR cameras that covers the focal length range equivalent to 85-310mm when converted to a 35mm format. The lens will allow owners of digital SLRs fitted with standard zoom lenses to enjoy with ease the professional-looking “pulling” and “compression” effects particular to telephoto lenses.
Lightweight and Compact Design Thanks to Optical System for Exclusive Use on Digital Cameras
Since the optical system is designed for exclusive use on digital cameras, the image circle is smaller, resulting in a compact package measuring 3.3 inches, accepting a 52mm standard filter and weighing a mere 10.4 ounces.
Revolutionary Minimum Focus Distance of 37.4 inches for 1:3.5 Macro Capability over the Entire Zoom Range
The 55-200mm zoom lens realizes an MFD (Minimum Focus Distance) of 37.4 inches over the entire zoom range, the top level of the closest focusing distance among tele-zoom lenses. Since the maximum magnification ratio at f=200mm is 1:3.5, you can enjoy easy and convenient close-up photography. (The Maximum Magnification Ratio of 1:3.5 is equivalent to 1:2.3 when converted to 35mm film format.)
Nine-blade Diaphragm Construction for Natural Out-of-focus Effect
Since the lens employs a nine-blade almost circular diaphragm construction, it provides naturally blurred background effects when a natural out-of-focus effect is desired. Such effects are done by using the shallow depth of field of a telephoto lens or in close-up photography, exploiting the outstanding specifications of 0.95m MFD over the entire zoom range and 1:3.5 maximum magnification ratio.
Optical System Uses Special Glass and is Optimized for Digital SLR Characteristics in order to Enhance Optical Quality in a Compact Design
The AF55-200mm zoom lens features an entirely optical design for optimizing the overall distribution of optical power while reducing various aberrations to the absolute minimum and achieving remarkable downsizing at the same time. In addition, an LD (Low Dispersion) glass element is 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 performance over the entire zoom range.
Optical Design Dedicated to Digital SLR Photography by Optimizing the Angles of Incidence of Light Rays Reaching the Image Sensor
The zoom lens uses a optical system designed to confine the changing angles of incidences of light rays reaching the imager within a certain scope over the entire image field by considering the effects of variances due to zooming.
Enhanced Peripheral Illumination
Peripheral light fall-off is minimized when compared with that of conventional lenses for film cameras, so images are uniformly bright from the center to the periphery.
Outstanding Resolution
Since the lens is designed exclusively for digital SLR photography, it provides high image quality resolution, contra
