October 1, 2006: Photokina 2006, which ends today, has seen the release by Sigma of six new designed-for-digital interchangeable lenses.
The 18-50mm F2.8 EX DC Macro maintains its f2.8 aperture throughout its zoom range. A minimum focusing distance of 20cm and a maximum magnification of 1:3, makes it ideal for close-up photography. Its design incorporates both glass-mould and hybrid aspherical lens technology for superior peripheral brightness, extremely high image quality as well as a compact and lightweight construction. Special Low Dispersion (SLD) and Extraordinary Low Dispersion (ELD) glass elements provide excellent correction of colour aberrations. The super multi-layer lens coating reduces flare and ghosting. Internal focusing allows this lens to be used with angle-critical filters and lens hoods. This lens is also available with Canon, Nikon, Pentax, Sigma and Sony mounts.
The new 18-200mm F3.5-6.3 DC OS lens. This high zoom ratio lens is exclusively designed for digital SLR cameras and features Sigma’s proprietary OS (Optical Stabiliser) plus two SLD (Special Low Dispersion) glass elements and two aspherical lenses provide for correcting all types of optical aberrations. The OS system uses two sensors inside the lens to detect vertical and horizontal movement of the camera and compensates for camera shake. Super multi-layer lens coating reduces flare and ghosting, while internal focusing allows the lens to be used with circular polarising filters and the petal-type lens hood supplied.
