User manual SIGMA 50MM F1.4 EX DG HSM

[. . . ] For more details, please refer to the camera’s instruction manual. Depending on the combination with camera some restrictions with its functions may result. ATTACHING TO CAMERA BODY AF AF G When this lens is attached to the camera body it will automatically function in the same way as your normal lens. [. . . ] You can adjust the focus by turning the focus ring. 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. 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. LENS HOOD 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. Attach the hood and turn clockwise until it stops rotation. 4) 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. 5 FILTER Only one filter should be used at the time. 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.
