Tamron 55-200mm Di II Zoom. The perfect next lens for your digital camera. This amazingly lightweight, compact telephoto zoom lens, is the perfect lens to use in addition to the one that came with your digital camera. Capture the smiles you love up close with a powerful zoom lens.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 easily enjoy the professional-looking pulling & compression effects of telephoto lenses.Designed for exclusive use on digital cameras, the image circle is smaller, resulting in a compact package measuring 83.0mm (3.3"),accepting a 52mm standard filter & weighing a mere 10.4oz.The 55-200mm zoom lens realizes a Minimum Focus Distance) of 37.4" 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 & convenient close-up photography.As the lens employs a 9-blade almost circular diaphragm construction, it provides naturally blurred background effects when an 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 & 1:3.5 maximum magnification ratio.The AF55-200mm zoom lens features an entirely new optical design for optimizing the overall distribution of optical power while reducing various aberrations to absolute minimum & achieving remarkable downsizing at the same time.In addition, an LD, Low Dispersion glass element is used to accomplish effective compensation of on-axis & lateral chromatic aberrations, a critical factor to enhance the optical quality. As a result, the lens provides outstanding optical performance over the entire zoom range.The zoom lens uses a new 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. Peripheral light fall-off is minimized compared with conventional lenses for film cameras, so images are uniformly bright from the center to the periphery. The lens provides high image quality resolution, contrast & flatness of image field.By the employment of Internal Surface Coatings & multiple-layer coating technology on ordinary elements, ghosting & flare due to reflections that occur when light enters through the front element & reflections caused by the imagers themselves are reduced to the absolute minimum.  Improvements have been made to the external design & the lens features a super hybrid mount made of highly durable, lightweight engineering plastic precisely molded around a highly durable stainless steel core.

I use this lens primarily for sports and outdoor activities.  It's been a great purchase, very durable and the zoom range is idea for getting a wide variety of shots.
