this large aperture telephoto zoom lens now incorporating Sigma's
Optical Stablization function, OS, our own anti-shake system which makes
viewing a stabilized image in the viewfinder possible for Sony and
Pentax 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,
measuring only 7.8” in length. For any serious photographer where the
70-200mm 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 focus capability.
