Sigma 150 mm F2.8 macro and optical stabilization

Photokina 2010: Sigma APO macro 150 mm introduced F2.8 EX DG OS HSM lens optical picture stabilization of that. Its predecessor is 150 mm F2.8 EX DG HSM, Sigma Hypersonic motor is fast, silent autofocus, and maximum magnification inherits the many features such as 1: 1 ratio. CROSS three elements that 7 promises an attractive rendition of a design used in elements of 13 groups of abnormalities and 9 blade circular diaphragm to minimize out-of-focus image area.

Sigma Corporation Sigma APO macro 150 mm F2.8 EX DG OS HSM, Sigma's original light stable equipment function that incorporates large diameter while the telephoto lens announced.

Successor to APO macro 150 mm F2.8 EX DG HSM, offers the latest optical technology was introduced in October 2004, the market for this new OS design. Floating two different lens system move group light path focusing on the different positions. This system, and then compensate for astigmatism distortion and spherical aberration provides 1: macro from the infinite very high optical performance.

Provide excellent correction of three SLD (special low dispersion) glass elements for all types of anomalies and reduces flare and ghosting Super multilayer films. This lens is excellent peripheral brightness, and provides for the opening of the largest sharp, high contrast images.

Proprietary OS-Sigma (light stabilizers,) feature with, this lens is approximately 4 stop in otherwise provides to use than a slow shutter speed. Quiet and high-speed auto focus, as well as HSM full-time manual focus capability (hyper Sonic motor) ensures.

This lens create a blur focus areas of the image to smooth, rounded 9 blade diaphragm. You can use an optional APO remote Converter lens-Sigma. focal length equivalent to 35 mm (24) • 225 mm (1. 5 x)
