An ultra-telephoto zoom lens/ which overcomes image blur caused by camera shake.
Sigma's OS (OPTICAL STABILIZER) system detects camera shake by utilizing two sensors/ and then the movement of an optical stabilizing lens group successfully compensates image blur. It is equipped with two optical stabilizer modes to compensate image blurring.
Mode 1 determines the camera shake in vertical and horizontal panning and compensates blurring/ this mode is effective when shooting static images,
Mode 2, detects the vertical camera shake/ and overcomes blurring. It is especially effective on moving subjects such as motor sports etc.
Two Special Low Dispersion (SLD) glass elements in the front lens group and one in the rear group offer effective control of color aberration. The lens features full-time manual focusing and a removable tripod collar. The rear focus system prevents the front of the lens rotating; a circular polarizing filter can be easily attached and used.
This lens is also equipped with a Zoom Lock Switch that eliminates "Zoom Creep". When this lens is used with the 1.4x EX or 2x EX Apo Tele Converters (optional), it becomes a 112-560mmF6,3-7.8 MF telephoto lens or a 160-800mm F9-11 MF ultra-telephoto lens respectively. The lens materials used in this new lens are lead and arsenic free ecological glass.
