The Sigma Corporation is pleased to announce the new 24-70mm F2.8 EX DG HSM.

This large aperture standard zoom lens covers focal lengths from 24mm and is housed in compact construction. The latest optical design provides an overall length of 94.7cm /3.7inch. It is ideal for general photography such as snapshots, portraiture and landscapes. The Super Multi Layer Coating reduces flare and ghosting. ELD (Extraordinary Low Dispersion) glass, two SLD (Special Low Dispersion) glass elements and three aspherical lenses provide excellent correction of all types of aberrations. Superior optical performance is ensured throughout the entire zoom range. This lens incorporates HSM (Hyper Sonic Motor), ensuring a quiet and high speed AF as well as full time manual focusing capability. This lens has a minimum focusing distance of 38cm/15in and a maximum magnification ratio of 1:5.3. The rounded 9 blades diaphragm creates an attractive blur. It is possible to attach the included petal-type hood to block out extraneous light.

The Sigma Corporation is pleased to announce the new ELECTRONIC FLASH MACRO EM-140 DG for Sony and Pentax cameras.

ELECTRONIC FLASH MACRO EM-140 DG is designed to work with both AF 35mm film and Digital SLR cameras. The EM-140 DG Macro Flash is ideal for photographing subjects in fine detail when the shadowless mode is used and is extremely effective for scientific and medical applications. Dual flash tubes can fire simultaneously or separately. Using only one flashtube creates shadow, which can give a three-dimensional feeling to the subject. The flash features a guide number of 14 w/ISO 100. The Modeling Flash function makes it possible to check for reflections and shadows before actually taking the flash picture. A wireless flash function is also available, when the EM-140 DG is used as master and the EF-530 DG SUPER as a slave unit for creating fine shadow details. High Speed Synchro and Exposure compensation functions are also available for advanced flash photography.
