Sophisticated Tamron Production Technology
Tamron manufacturing processes are certified to demanding ISO 9001 standards, an internationally recognized indicator of the most thorough quality control.
Tamron’s high-power zoom lenses come out of a factory that is well known for delivering on its world-class capabilities, and is widely respected for its unwavering policy of delivering excellent quality products that meet the total satisfaction of its valued customers.
Below is a list of some of the unique technologies and their descriptions:
Name of Technology
|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.|
|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,|
|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.|
|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.|
|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.|
|Hybrid Aspherical Elements||Through the effective application of Hybrid
Aspherical Technology, one lens element can take the place of multiple elements without compromising performance.
|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.|
|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.|
|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.
|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.
|Piezo Drive (PZD)||The Piezo Drive (PZD) is an advanced ultrasonic, autofocus (AF) motor based on the latest piezoelectric technology—the standing wave principle.|
|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.|
