Advanced optical technology

Three LD (Low Dispersion) elements are effectively deployed to correct chromatic aberrations, a challenging problem when shooting at long distances and at long focal-length settings. Tamron's eBAND Coating and BBAR (Broad-Band Anti-Reflection) Coating help suppress flare and ghosting for class-leading image quality.

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. This nano-structured layer coupled with the sophisticated multiple layer coatings underneath, yields significant anti-reflection properties, efficiently reducing undesired flare and ghosting to an absolute minimum to deliver sharp, crisp images.

Moisture-resistant construction

Moisture-resistant construction helps prevent moisture from penetrating the lens.


 

USD (Ultrasonic Silent Drive)

The quiet high-torque USD motor ensures a speedy and accurate autofocus response.

VC (Vibration Compensation)

VC (Vibration Compensation) is Tamron's proprietary image stabilization system.
Tamron's VC is a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three ceramic ball bearings. The VC lens elements are held in place only by contact with the ceramic ball bearings, achieving smooth movement with little friction. And since the VC mechanism is moved in parallel using only the motorized control, the mechanical structure has been simplified, enabling the development of a more compact lens.
