The Sigma 17-35mm f2.8 EX aspherical HSM lens combines a fast f2.8-f4 maximum aperture with an ultra-wide-angle zoom of 17-35mm. Also, by incorporating aspherical lens elements in the front and rear lens groups, it corrects spherical aberration that could distort your images. The internal focusing system prevents the deterioration of optical quality when you are at a close distance to your subject, and it eliminates the rotation of the front barrel during focusing. The lens materials used in this lens are lead-free and arsenic-free ecological glass. This model is dedicated to Pentax AF SLR cameras.

The lens is equipped with Sigma's own unique OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group to effectively compensate for camera shake. This system offers the use of shutter speeds approximately 4 stops slower. It also automatically detects movement of the camera and compensate for camera shake when shooting moving subjects such as motor sports. Its compact construction has an overall length of 88.5mm (3.5"), maximum diameter of 74mm (2.9") and weight of just 450g/15.9oz (Sigma mount). This lens has a minimum focusing distance of 35cm (13.8") at all focal lengths, and has maximum magnification of 1:3.8, making it ideal for close-up... Less
