The new lens features optical construction consisting of three LD (Low Dispersion) lens elements to mitigate chromatic aberrations, plus Tamron’s anti-reflection eBAND (Extended Bandwidth & Angular-Dependency) Coating to help eliminate ghosting and flare.
The newest Tamron lens models feature a high-speed Dual MPU (Micro-Processing Unit) control system, and so will the new 100-400mm. The system is designed to provide the lens with “quick and highly responsive autofocus performance and outstanding vibration compensation.”
Other features include a 59-inch minimum object distance, a 1:3.6 max magnification ratio and a fluorine coating to protect the moisture-resistant lens from the elements. The 100-400mm is compatible with Tamron’s 1.4x teleconverter and the TAP-in Console for lens adjustments.
