EX series large aperture zoom lens designed specially for use with digital SLR cameras with a minimum focusing distance of 20cm.

 Minimum focusing distance of 20cm with a maximum magnification of 1:3
 SLD & Aspherical lenses offer excellent correction for various optical aberrations
 SLD and ELD lenses offer excellent correction of color aberrations
 New optical design minimizes vignetting

This lens has a large aperture of F2.8 throughout the entire zoom range, a minimum focusing distance of 20cm (7.9”) and a maximum magnification of 1:3, making it ideal for close-up photography.

Specially designed to suit the characteristics of digital SLR cameras this lens provides a high level of optical performance. Its design incorporates both glass-mould and hybrid aspherical lens technology which offers extremely high image quality as well as a compact and lightweight construction. Minimal vignetting and superior peripheral brightness is ensured.

A Special Low Dispersion (SLD) glass and Extraordinary Low Dispersion (ELD) lens elements provide excellent correction of color aberrations. The super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras. High image quality is assured throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood (supplied) plus circular polarizing filters.
