Sigma EX telefoto zoom objektiv

Sigma's EX is the second generation of this large aperture telephoto zoom lens incorporating Sigma's optical stabilization function, OS, anti shake system which makes viewing a stabilized image in the viewfinder possible for users if chosen. Two FLD glass elements, which have the performance equal to fluorite glass, have also been added along with three SLD glass elements, all which provide excellent correction of color aberration. In spite of the additions of all of these features, Sigma has managed to make the lens more compact than its predecessor.For any serious photographer where the 70-200 mm focal range is often the most important second lens to own after the initial standards lens or mid range zooms. The fast aperture is extremely useful and important in low light environments or when shooting fast moving situations where a higher shutter speed demands maximum lights thru the lens. HSM ensures quiet and high speed AF as well as full time manual focuses capability. Super multi layer lens coating reduces flare ghosting and assures high image quality throughout the entire zoom range. This lens is equipped with a petal type hood. Its exceptional versatility as an all-around lens is perfect for journalists and wedding photographers.
