User manual SIGMA 10MM F2.8 EX DC DIAGONAL FISHEYE HSM

[. . . ] The specialized design gives these lenses the ideal properties for digital cameras. An image sensor element larger than those corresponding to APS-C cannot be used in digital cameras or 35mm SLR cameras. If such an element is used vignetting will occur on the picture surface. [. . . ] If you wish to focus manually, set the focus mode switch on the lens to the “M” position. You can adjust the focus by turning the focus ring. Please refer to camera’s instruction manual for details on changing the camera’s focusing mode. 2 M 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. This lens also permits manual focusing even in the autofocus mode. 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. Special allowance is made for this at the infinity setting. 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. Please ensure the subject is in the AF frame before shooting. 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. 3) FILTER Filters cannot be mounted on the front of the lens. If you wish to use filters, please use gelatin type. Please cut the gelatin filter, using the guide plate accessory as a pattern, and insert the filter into the filter holder at the rear of the lens. [. . . ] 8 oz) Dimensions and weight include the SIGMA mount. Sørg for at disse er rene for at sikre god forbindelse. For at undgå beskadigelse af objektivet, sørg da for at placere det med fronten nedad ved objektivskift. [. . . ]
