Sigma AF 18 200mm f 3 5 6 3 DC OS Optical Stabilizer Zoom Lens for Canon Digital SLR Cameras
The Sigma 18-200 F3.5-6.3 DC OS HSM Lens incorporates an Optical Stabilizer function and is exclusively designed for digital SLR cameras. It is perfectly suitable for low light conditions whether indoors, at dusk, or in telephoto range. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It also automatically detects panning movement of the camera and compensates for camera shake when shooting moving subjects such as motor sports. SLD (Special Low Dispersion) glass and aspherical glass provide excellent correction for all types of aberrations. This lens has a minimum focusing distance of 45cm (17.7″) throughout the entire zoom range and has a maximum magnification of 1:3.9. Since the inner focusing system means the front of the lens does not rotate, optional circular polarizing filters and the supplied petal-type hood can easily be used. A magnification scale is displayed on the lens barrel, ensuring ease of use. A zoom-lock switch mechanism is provided to prevent the lens from creeping due to its own weight. 69.3 – 7.1 degrees (Sigma SD format) angle of view 7 Diaphragm Blades F22 Minimum Aperture 45cm / 17.7 Minimum Focusing Distance 1 – 3.9 Maximum Magnification Petal Lens Hood Dimensions – Diameter 79mm x Length 100mm Weight – 21.5 ounces (610 grams)

Sigma 10 20mm f 4 5 6 EX DC HSM Lens for Canon Digital SLR Cameras
10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with digital SLR cameras. Wide angle of view (102.4 degrees at 10mm and 63.8 degrees at 20mm) offers the photographer greater freedom of expression. 3 Special Low Dispersion (SLD) glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration. This lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 24cm at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently. Angle of View – 102.4 – 63.8 degrees 6 Diaphragm Blades Minimum Aperture F22 Minimum Focusing Distance – 24cm/9.4 inches Maximum Magnification – 1 – 6.7 Filter Size – Diameter 77mm Lens Hood Petal Hood Dimensions – Diameter 83.5mm x Length 81mm, 3.3 x 3.2 inches Weight – 470 gram (16.6 ounces)
