Sigma DP2, A huge step forward.

Sigma DP2, A huge step forward.



Back in 2008 we tested the Sigma DP1, and were amazed by its pictures, but unfortunately the DP1 was not made for the average user but rather the Photo savvy amateur who take time to shoot each pictures.

Today, at the PMA, Sigma announced the DP2, and claimed that this new version is 20% snappier than the DP1, which is actually a huge step forward for this already amazing point and shoot. The ISO range has also been widely improved and the DP2 has now an ISO range up to 3200… Anyway we are looking forward to get this baby in hands to give you our live impression on this improved DP2.

High ratio zoom lens housed in a compact construction and incorporating Sigma’s original OS (Optical Stabilizer) function.

The Sigma Corporation is pleased to announce the launch of the new APO 150-500mm F5-6.3 DG OS
HSM.

  • Incorporating Sigma’s original OS (Optical Stabilizer) function.
  • An ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows short perspective.
  • Three SLD glass elements and a rear focus system provide optimum image quality throughout the entire zoom range.

This ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows photographers to bring the subject close and short perspective. Sigma’s original OS (Optical Stabilizer) function offers the equivalent of using a shutter speed approximately 4 stops faster. 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. A removable tripod socket (TS-31) is included as a standard component.
*1 OS function is not available.
*2 If the camera body does not support HSM motor, AF does not work.
