Name of Technology

Description
LD Low Dispersion (LD) Glass Low Dispersion (LD) glass elements in a lens help reduce chromatic aberration, the tendency of light of different colors to focus at different points on the image plane.
XLD Extra Low Dispersion (XLD) Lens Extra Low Dispersion (XLD) lens elements made from specialized ultra-high grade glass allow Tamron lens designers to achieve much greater control over chromatic aberration (color fringing) and magnification aberrations,
AD Anomalous Dispersion (AD) Anomalous Dispersion (AD) glass is a special type of optical glass that is used to achieve more precise control of chromatic aberrations, thereby enhancing overall imaging performance.
SP Super Performance (SP) The Tamron Super Performance (SP) series is a line of ultra-high-performance lenses designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality.
XR Extra Refractive Index (XR) glass Extra Refractive Index (XR) glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimizing optical aberrations.
ASL Hybrid Aspherical Elements Through the effective application of Hybrid
Aspherical Technology, one lens element can take the place of multiple elements without compromising performance.
eBand New eBAND (Extended Bandwidth & Angular-Dependency) Coating This new coating technique developed by Tamron deploys a nano-structured layer (1nm = 1/1,000,000mm) of ultra-low refractive index, with dimensions smaller than the wavelengths of visible rays of light.
VC Vibration Compensation (VC) Tamron’s unique Vibration Compensation (VC) mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking.
IF Internal Focusing (IF) System Internal Focusing (IF) provides numerous practical benefits to photographers including
a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing.
ZL Zoom Lock (ZL) Feature A simple convenience feature that prevents
undesired extension (creep) of the lens barrel when carrying the camera/lens unit on a neck strap.
PZD Piezo Drive (PZD) The Piezo Drive (PZD) is an advanced ultrasonic, autofocus (AF) motor based on the latest piezoelectric technology—the standing wave principle.
USD Ultrasonic Silent Drive (USD) Ultrasonic Silent Drive (USD) is an ingeniously upgraded autofocus-drive system developed by Tamron to deliver the extraordinary auto-focusing speed and precision needed to capture every nuance of high-speed sports action, along with virtually noiseless operation as required for discreet picture taking.
