Features
Internal Focusing
The internal focusing mechanism allows the front of the lens to remain stationary and to easily accommodate specialty filters, such as polarizing filters.
Two Aspherical Elements
A lens design incorporating elements ground so the curve of the surface does not describe an arc of a circle. Especially useful in reducing distortion in wide angle lenses.
UD Element
UD glass is one of the new technologies to open new possibilities to develop the zoom lenses with low weight and high optical performance. UD elements make it possible to correct chromatic aberrations whilst maintaining low weight.
