Sonic Motor) ensures quiet and high speed AF, while allowing full-time manual
focus override. The addition of the optional APO TELE CONVERTER produces a
1000mm ultra telephoto zoom lens.
Covering a range of focal lengths up to ultra telephoto
This lens is ideal for many types of photography such as motor sport, air
planes, macro and wildlife. By rotating the zoom ring, it is possible to change
the focal length easily from a standard focal length to an ultra telephoto
range. This lens has an equivalent angle of view of a 75-750mm lens when
used on digital cameras with APS-C size image sensors.
Sigmas own unique OS (Optical Stabilizer) technology
The lens is equipped with Sigmas own unique OS (Optical Stabilizer)
function. This system offers the use of shutter speeds approximately 4 stops
slower than would otherwise be possible, making telephoto shooting easy. Mode 1
is ideal for general photography and Mode 2 is designed for panning subjects
such as racing cars. For Sony and Pentax mount, the built-in OS function of this
lens can be used even if the camera body is equipped with an anti-shake
function. As compensation for camera shake is visible in the view finder, the
photographer can easily check for accurate focus and ensure there is no subject
Excellent Optical Performance
This lens features four SLD (Special Low Dispersion) glass elements,
providing excellent correction of color aberration throughout the entire zoom
range. The super multi-layer coating reduces flare and ghosting and ensures high
contrast images. This lens is equipped with a read focus system that minimizes
fluctuation of aberration caused by focusing. High image quality is assured
throughout the entire zoom range.
The close focusing capability
This lens has a maximum magnification of 1:3.1 (at the focal length of
200mm). It enables photographers to get close up to small subjects and eliminate
distracting parts of larger subjects.
HSM (Hyper Sonic Motor)
The rear focus mechanism and HSM (Hyper Sonic Motor) ensures quiet and high
speed AF as well as full time manual focus capability.
Optional APO Tele-Converter
The addition of the optical 1.4x EX DG APO or 2x EX DG APO Tele Converters

mechanism makes it possible to use the custom bayonet "Petal-type Hood", which
prevents extraneous light from degrading the image quality. The filter size of
this lens is Diameter 95mm and the lens is supplied with a step down ring
enabling digital cameras with an APS-C size image sensor to use an Diameter 86mm
