The Tamron SP 17-50mm f/2.8 XR Di II LD is a lightweight, compact fast zoom lens that is designed exclusively for Digital SLR Cameras, with 17mm Wide Angle Coverage The lens covers virtually the same angle as focal lengths of 26-78mm when converted to a 35mm format. The wide-angle focal length is established at 17mm (26mm equivalent) to obtain a wider angle of view than ordinary standard zoom lenses. Since the lens is designed exclusively for APS-C sized digital cameras, the image circle diameter has been reduced.
The use of XR (Extra Refractive Index) glass optimizes the overall distribution of optical power and also reduces various aberrations to the absolute minimum. In addition, two hybrid aspherical elements maintain imaging performance and help compress the entire optical system. Furthermore, an LD (Low Dispersion) glass element is used to accomplish effective compensation of on-axis and lateral chromatic aberrations.
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.
By employing “Internal Surface Coatings” and new multiple-layer coating technology on ordinary elements, ghosting and flare due to the reflections that occur when light enters through the front element and reflections caused by the imagers themselves are reduced to the absolute minimum.
This Lens has a large aperture in lightweight, compact design thanks to complicated mechanisms that are built into the compact body for excellent portability and ease of use. In addition, a complex triple cam structure where cams zoom and focus within a three-layer lens barrel has been further developed to improve AF focus precision for close-in shots and torque irregularity when zooming in and out. Additionally, the engineering of the lens has been completely overhauled to downsize its parts and to increase their precision and durability.
A zoom lock prevents unwanted barrel extension when carrying the lens/camera combination. A flower shaped lens hood is also included.
