Overview
  • 1Description

The Sigma 70-200mm f/2.8 II EX APO Macro HSM telephoto zoom lens has a large maximum aperture of f/2.8 which remains constant throughout the zoom range, an improved optical performance, macro capabilities, and is optimized for digital SLR cameras. It also features super multi-layer coating, which reduces flare and ghosting.

This Macro lens has improved macro capability, with a minimum focusing distance of 3.3' (100cm) and maximum magnification of 1:3.5. All zooming and focus movement is achieved internally, allowing for a constant length and great resistance to dust and moisture. It comes rendered in a hard coated, baked black EX crinkle finish. The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function.

This lens can also be used with the 1.4x EX or 2.0x EX APO Tele Converters (optional), becoming a 98-280mm f/4 autofocus telephoto zoom lens or a 140-400mm f/5.6 autofocus telephoto zoom lens respectively.

Note: HSM lenses can only autofocus with camera bodies that support Pentax's SDM feature. This is the same limitation as Pentax's own SDM lenses.

DG Lens Design
The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor.
HSM (Hyper Sonic Motor)
Hyper Sonic Motor provides smooth, silent AF with full time manual focus override.
ELD & SLD Elements
This lens uses three ELD (Extraordinary Low Dispersion) elements and two SLD (Special Low Dispersion) elements for utmost correction against chromatic aberrations.
Tripod Mount
A rotating tripod mount can be conveniently detached if required.
