Tamron SP 70-200mm f/2.8 Di VC USD Lens for Nikon is a high speed standard to telephoto zoom lens with the fast f/2.8 maximum aperture throughout the zoom range. Designed for full-size SLR and DSLR cameras, it offers superior image quality accentuated by advanced Vibration Compensation (image stabilization) and an Ultrasonic Silent Drive Motor for quiet, smooth and precise autofocus.
USD (Ultrasonic Silent Drive) Motor is the power for a fast and quiet autofocus drive that works in harmony with continuous manual focus mechanism.
VC (Vibration Compensation) is Tamron’s proprietary image stabilization mechanism which reduces the effects of camera shake to deliver sharp images in low light and at slower shutter speeds. It is a newly developed three coil system that employs a lighter moving coil mechanism which contributes to its improved performance and overall compact design.
XLD and LD Optics
One special XLD (Extra Low Dispersion) and four LD (Low Dispersion) elements minimize chromatic aberrations.
Tamron’s advanced multi-layer coating technology dramatically improves lens performance by reducing flare and ghosting for crisper, clearer images
