User manual SIGMA 35MM F1.4 DG 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. NIKON AF TYPE CAMERAS This lens functions in the same way as a G Type auto-focus Nikon lens (without an aperture ring). For more details, please refer to the camera’s instruction manual. [. . . ] 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. aF AF AF M 2 AF AF 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. ( 3) F16 F16 DEPTH OF FIELD SCALE The depth of field scale helps you to check the depth of field (the zone of sharpness) of your composition. For example in figure (3), the depth of field zone is shown when the aperture F16 is used. 5) LENS HOOD 4 A bayonet type detachable hood is provided with the lens. This lens hood helps to prevent flare and ghosted images caused by bright illumination from outside the picture area. 4) When taking photographs using the built-in flash, it is advisable to remove the lens hood so as to avoid cutting off any of the flash output, which could cause a shadow in the picture. In order to place the lens and hood into the storage case, you must first remove the hood, then replace it on the lens in the reverse position. Two or more filters and/or special thicker filters, like a polarizing filter, may cause vignetting. When using a polarizing filter with AF camera, use the “circular” type. BASIC CARE AND STORAGE Avoid any shocks or exposure to extreme high or low temperatures or to humidity. [. . . ] Vid objektivbyte, se till att objektivets front hålls nedåt för att undvika att objektivet skadas. J E The glass materials used in the lens do not contain environmentally hazardous lead and arsenic. Använder du polarisationsfilter se till att det är av den ”cirkulära” typen som passar till autofokus. [. . . ]
