The use of specialized, high quality glass materials assures accurate color reproduction and superior sharpness, perfect for today’s high-pixel-density cameras. Optical construction (17 elements in 12 groups) uses 2 XR (Extra Refractive Index) elements, 3 LD (Low Dispersion) elements, 3 GM (Glass-Molded aspherical) and one hybrid aspherical lens element. Together they minimize axial chromatic aberrations, transverse chromatic aberrations, spherical aberrations and distortion, and allow a compact design that achieves superior image quality.
Besides Tamron’s original VC (Vibration Compensation) system, the A032 has an MPU dedicated to VC processing, for the highest vibration compensation in its class*, with a CIPA image stabilization level of 5 stops**. Enjoy jitterfree shooting and more flexibility — even in low light.
* Among 24-70mm F/2.8 interchangeable lenses for DSLR cameras (as of May, 2017; Tamron)
** CIPA Standard Compliant. For Canon:EOS-5D MKIII is used. For Nikon:D810 is used.
*** A new control system using two high-performance MPUs (micro-processor units)
The A032 is equipped with its own MPU (micro-processor unit), with embedded DSP (digital signal processing) blocks that enable high-speed digital signal processing, achieving both excellent responsiveness to signals from the camera and high-precision AF performance.
The A032 features Tamron’s proprietary eBAND(Extended Bandwidth & Angular-Dependency) Coating and BBAR (Broad-Band Anti-Reflection) Coating, to combat ghosting and flare. A nano-structured layer and conventional multiple-layer coatings deliver superior anti-reflection properties.
The lens hood is equipped with a locking mechanism, which prevents detachment due to unintentional contact during use.
The optional TAP-in Console provides a USB connection to your personal computer, enabling you to easily update your lens’s firmware as well as customize features including fine adjustments to the AF and VC.
The VC Image Stabilizer delivers sharp and shake-free images, as well as a smooth viewfinder image.
Powerful ultrasonic motor for quick and dynamic subjects. It is extremely quiet, precise and allows manual control at any time.
Nano-structured lens coating to protect against unwanted reflection and ghosting.
Protects against undesired extension of the lens barrel.
