The Sigma 70-200mm f/2.8 EX DG APO OS HSM for Pentax is the second generation of large-aperture telephoto zoom lenses incorporating Sigma's OS (Optical Stabilizer) anti-shake system. It offers the equivalent of shooting at shutter speeds 3 to 4 stops slower than without OS, thus allowing handheld telephoto zoom shooting even in poorly lit conditions. Its HSM ensures quiet and high speed AF as well as full-time manual focusing.
It features a large maximum aperture of f/2.8 that remains constant throughout the zoom range, making it incredibly valuable when shooting in low light situations such as weddings or other events. It is also great when shooting fast-moving subjects such as sports, when fast shutter speeds are needed to capture fleeting moments. The 70-200mm f/2.8 is fast and versatile and at a length of 7.8 (19.8cm) will be a tool that seldom sees the inside of your camera bag. The lens comes with a petal-type lens hood plus an adapter to extend its length for users with APS-c cameras.
Note: This lens is optimized for full-frame Nikon DSLRs and may also be used with smaller APS-c size sensors but it will increase focal length to about 100-300mm with most cameras.
Note: When using the OS function of the lens with a camera which incorporates a stabilizer unit, please turn the camera's stabilizer unit off.
Note: The Pentax mount Tele Converter cannot be used with this particular lens.
Note! Optical Stabilizer (OS) function will not work with film SLR cameras
