The 28-300mm F3.5-6.3 MACRO lens covers focal lengths from 28mm wide angle to 300mm telephoto macro capability, allowing a reproduction ratio of 1:3With a multi layer lens coating and lens design to reduce flare and ghosting, this lens features one Special Low Dispersion (SLD) glass element and one aspherical lens in the front lens group, and one SLD glass element and three aspherical lenses in the rear lens group for correction for all types of aberrations.The inner focusing system allows for stability and compactness throughout the focal lengths.

This telephoto zoom lens incorporates Sigma’s original OS (Optical Stabilizer) function and is housed in a compact construction.  With a focal range of 70-300mm, this is a good complement to a standard wide lens to complete your photographic needs from wide to telephoto. Applications include portraiture and general photography. The OS function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible while the SLD (Special Low Dispersion) glass element provides excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range.

This large aperture standard zoom lens, recommended for both Digital SLR and 35mm Film SLR Cameras, has a wide F2.8 aperture at all focal lengths – ideal for low light shooting condition,s creative portraiture and sports photography.
Coated with a Super Mulit-Layer coating to reduce light reflections, the Sigma 24-70mm F2.8 EX DG Macro uses Special Low Dispersion (SLD) technology to combats colour aberration and features a Dual Focus System.
Although not a true macro lens, with a magnification ratio of 1:3,8 this lens will still be useful for close-up photography applications.

The SIGMA 18-250mm F3.5-6.3 DC OS HSM incorporates Optical Stabilizer which provides not only an anti-shake function for the camera body, but also compensates for image shaking in the view finder as the Optical Stabilizer is built in to the lens.

This wide angle to short telephoto lens is great for vast, sweeping landscapes, very wide group shots as well as close ups from far away for creative portraiture.
The 18-250mm incorporates four Special Low Dispersion glass elements and three aspherical lens elements for excellent image quality throughout the entire zoom range, an inner focusing system which eliminates front lens rotation, and a super multi-layer coating reduce the ghost in the backlight photography.
