Digital Cameras Photo Reviews of Sigma 18-50mm f/2.8 EX DC SLD ELD Aspherical Macro Lens for Olympus and Panasonic Digital SLR CamerasCustomer Review: Impressive Quality and Performance Summary: 5 Stars
After long research felt skeptical about the quality at F2.8 but decided to get it. I am amazed with the pictures that I took with this lens at all apertures. When compare to the kit lens even at F2.8 the pictures taken using Sigma are way sharper, few reviewers mention about soft image at F2.8 but perhaps my results are different as maybe the kit Olympus lens which is made in China failed quality control and as a result I end up with bad lens. I accepted the quality as standard and would probably never know. I'm very happy with this lens and highly recommend them to anyone.
Description of Sigma 18-50mm f/2.8 EX DC SLD ELD Aspherical Macro Lens for Olympus and Panasonic Digital SLR CamerasThe Sigma Corporation is pleased to announce the launch of the new 18-50mm f/2.8 EX DC MACRO lens. This lens has a large aperture of f/2.8 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-mold 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. Special Low Dispersion (SLD) and Extraordinary Low Dispersion (ELD) glass 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
