This lens features 18 elements in 13 groups, aspherical elements, low dispersion elements, an ultrasonic silent drive motor, vibration compensation with three ceramic ball bearings, and a new eBAND coating. According to them, the new coating is “A nano-structured layer (1nm = 1/1,000,000mm), with dimensions smaller than the wavelengths of visible rays of light, is deployed on top of multiple coating layers to maximize efficiency.”
“Reflections occur at the interface between the lens and the air because of the difference in refractive indices of the two substances. The nano-structure of the eBAND Coating renders an extremely low refractive index by minimizing the differential with that of air while actively inducing air to its own structure, thus significantly suppressing the extent and degree of reflections.”
More tech specs are after the jump. We also have no word yet on pricing.
