User manual SIGMA 8-16MM F4.5-5.6 DC CIRCULAR HSM

[. . . ] In order to get the maximum performance and enjoyment out of your Sigma lens, please read this instruction booklet thoroughly before you start to use the lens. The specialized design gives these lenses the ideal properties for digital cameras. 1 An image sensor element larger than those corresponding to APS-C cannot be used in digital cameras or 35mm SLR cameras. [. . . ] Please refer to camera’s instruction manual for details on changing the camera’s focusing mode. For Nikon, Pentax and Sony mounts, it is only possible to use AF with camera bodies which support motors driven by ultrasonic waves such as HSM. AF will not function if the camera body does not support this type of motor. With the camera set to the One-Shot AF (AF-S) mode, it is possible to manually override the autofocus while the shutter release button is pressed halfway. When operating this lens in manual focus mode, it is recommended that correct focus be confirmed visually in the viewfinder rather than relying on the distance scale. This is due to possible focus shift resulting from extreme changes in temperature which cause various components in the lens to expand and contract. This lens has a short focal length and gives a wide depth of field and wide focusing area in front of and behind the subject. If the subject is too small, it may not be possible for the camera’s AF sensor to focus on it. Zooming Rotate the Rubber grip on the zoom ring to the desired position. AF AF PREVENTION OF FLARE AND GHOST Because of the extremely wide angle of view of this lens, flare and ghosting may occur much more easily than with other lenses. When you take a picture with this lens, please pay special attention to flare and ghosting which can occur when shooting near or directly into the sun or other very bright lights. FLASH PHOTOGRAPHY Built-in flash of your camera may not cover angle of view of this lens, and this may cause light fall-off at the corners. When external flash is used, flip wide panel of your flashgun down to cover flash’s head, before taking picture. For extended storage, choose a cool and dry place, preferably with good ventilation.
