Sigma C 18-300mm F/3.5-6.3 DC Macro OS HSM Lens
For Pentax K Mount
The Sigma C 18-300mm F/3.5-6.3 DC Macro OS HSM is a wide to super telephoto zoom designed for cameras with a APS-C (1.5X) sensor. This variable-aperture zoom covers a 18mm to 300mm focal-range. It provides the same field of view as a 27-450mm lens on a Full-Frame camera. An optical Image Stabilization System built into this lens compensates for camera shake.
This zoom can focus down to 39cm from the imaging plane which gives it a maximum magnification of 0.33X. The lens supports autofocus and features a switch to disengage AF for focusing manually. A built-in focus motor is used to set the focus-distance. It allowed Sigma to optimize the motor precisely for this lens in order to maximize performance.
This version has a Pentax K lens mount. Follow this link for all current compatible digital cameras: Pentax K mount cameras with APS-C (1.5X) sensors. Sigma also made this lens available for Canon EF, Nikon F, Sigma S, Sony A mounts.
