17-50mm F/2.8 Di II VC SP

– Phased Out –

Make the Most of Your Light. With Perfect Stability.

The compositional options afforded by the SP 17-50mm F/2.8 Di-II VC’s wide-to-moderate-telephoto zoom characteristics are prized by experienced photographers, rendering a picture angle range approximating a 26-78mm lens on a full frame DSLR or a 35mm SLR. A fast and constant F/2.8 maximum aperture allows cluttered backgrounds to be softly obscured, additional freedom in lowlight conditions and added viewfinder brightness.
State-of-the art properties, including XR (Extra Refractive Index) and LD (Low Dispersion) glass in an optical formula employing 19 elements and 14 groups—assures sharpness, optimal contrast and breathtaking image fidelity. Its form factor and handling characteristics can be traced to the use of aspherical element design and internal focus. Tamron’s proprietary tri-axial VC (Vibration Compensation) image stabilization adds to image sharpness and further expands low-light shooting freedom by combating image blur resulting from camera shake. Tri-axial VC addresses the adverse effects of camera shake in three planes making it possible to shoot handheld at as many as four shutter speeds slower than would otherwise be possible.

Di-II lenses are performance-engineered expressly for digital SLR cameras with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm.

VC (Vibration Compensation) – The VC Image Stabilizer delivers sharp and shake-free images, as well as a smooth viewfinder image.

Super Performance – Tamron’s Super Performance series delivers a range of lenses that meet the highest standards.

$Extra Refractive Index$

XR (Extra Refractive Index) Glass – A special glass with a particularly high refractive index for greater performance and a compact lens design.

ASL – Hybrid aspherical elements ensure unique image quality and compactness.

LD (Low Dispersion) – Lens element for greater image sharpness and the correction of chromatic aberration.

Internal Focusing (IF) System – The extension length of the lens does not change during focussing and the close focussing distance is significantly reduced across the entire focusing range.
