Sigma releases the the 150-500mm for Sony and Pentax mounts

The Sigma Corporation is pleased to announce the launch of the new APO 150-500mm F5-6.3 DG OS HSM for Sony and Pentax.
This ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows photographers to bring the subject close and short perspective. This lens has an equivalent field of view of a 225-750mm when used on digital SLR cameras with an APS-C size image sensor. Sigma’s original OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower. As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement.It is ideal for sports, wildlife and landscape photography with handheld shooting. Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with a rear focus system that minimizes fluctuation of aberration caused by focusing. The super multi-layer lens coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The addition of the (optional) 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 210-700mm F7-9 MF ultra-telephoto zoom lens or a 300-1000mm F10-13 MF ultra-telephoto zoom lens respectively (For Sony fitting only). A removable tripod socket (TS-31) is included as a standard component.

You may know me better as 'Admin', as I work more behind the scenes to keep PhotoComment running smoothly, so here is a short history of how I got here. I started working in a camera store right out of high school having never picked up a camera before. I spent a few years working there and then moved to wholesale and then made a big change and went into the cycling industry for a few years, however I could not stay away and made the move back into the photography industry and have been working with PhotoComment since March 2008. It has become a passion and a labor of love to bring the best photographic content to you.
