A ultra wide angle zoom lens incorporates the latest optical design and provides superior performance. FLD (F Low Dispersion) glass elements, which have performance equal to fluorite, and SLD (Special Low Dispersion) glass elements provide excellent correction of colour aberration. Aspherical lenses give advanced performance with a compact and lightweight construction and ensure high image quality throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting and incorporation of HSM ensures quiet and high speed autofocus as well as full-time manual focus capability. This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures.
- Four FLD Glass elements – performance equal to fluorite – ultra high light transmission and low refractive index, plus high anomalous dispersion – will correct secondary spectrum chromatic aberration, not possible to achieve with normal optical glass
- One SLD (Special Low Dispersion) Glass element – excellent correction of chromatic aberration
- Three aspherical elements and one hybrid aspherical element to retain edge-to edge sharpness right through the zoom range
- Super Multi-Layer Coating for virtually eliminating ghosting and lens flare
