Tamron [B005N II] SP AF17-50mm F2.8 XR Di II VC LD Compatible With Nikon
The new SP 17-50mm F/2.8 XR Di II VC covers the very popular 17-50mm focal length range (equivalent to 26-78mm in the full-frame 35mm format ) making it extremely versatile. Its wide aperture and outstanding performance provide practical advantages in low-light shooting and aesthetic image control, thereby enriching the user’s range of creative expression. The new lens delivers impressive sharpness and striking contrast over its entire focal-length and aperture range, and at its maximum aperture of f/2.8 it produces beautiful images enhanced by shallow depth of- field, and smooth, natural transitions in out-of-focus areas of the image (i.e. excellent bokeh.) The new lens is equipped with Tamron’s proprietary Vibration Compensation (VC) image stabilization mechanism, which controls the effects of camera shake in three planes. VC provides more opportunities for sharp hand-held photography at the slow shutter speeds needed when shooting in low-light conditions (e.g. night or indoor scenes) dramatically enhancing the user’s level of photographic freedom.
A masterpiece of innovative optical design, this compact, lightweight, high performance standard zoom (26-78mm equivalent) delivers a fast F/2.8 aperture over its entire focal-length range for maximum creative flexibility. To maintain critical sharpness when shooting handheld it includes VC (Vibration Compensation), Tamron’s state-of-the-art, tri-axial image stabilization system. Three compound aspheric elements, special LD glass, and BBAR coatings ensure superb correction, color fidelity, and freedom from flare. A minimum focus distance of 0.29m (11.4 inches ) offers exciting close-up opportunities.

Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm.
Vibration Compensation (VC)
Handheld camera shake is the leading cause of blurry and unsharp pictures. Several leading companies now make lenses with built-in optical image-stabilization systems that sense the amplitude and direction of the shake and compensate by moving optical groups within the lens. Tamron’s exclusive new Vibration Compensation (VC) system that’s built into the Tamron AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) Macro and the Tamron AF18-270mm F/3.5-6.3 Di-II VC LD Aspherical (IF) Macro lenses performs a similar function, but it executes it much more effectively due to its innovative breakthrough design
- VC delivers blur free - handheld images for incredible results
- VC mechanism employs a three-coil system
- Lens element compensates for vibration using 3-steel balls (making movement quiet & smooth)
- Exceptional images at slower shutter speeds – reduces the need for a tripod
- Bring out contrast to motion & stillness
- Eliminate the need to shoot with a Flash

Low Dispersion (LD)
Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)
