[. . . ] Press the shutter button halfway down, confirm the image in the viewfinder is stable then take the picture.

[. . . ] If such an element is used vignetting will occur on the picture surface. If you use SD14 or SD10 or SD9 digital camera, corresponding angle of view will be 30-425mm. ATTACHING TO CAMERA BODY When this lens is attached to the camera body it will automatically function in the same way as your normal lens. Please refer to the instruction booklet for your camera body. On the lens mount surface, there are a number of couplers and electrical contacts. Please keep them clean to ensure proper connection. To avoid damaging the lens, be especially sure to place the lens with its front end down while changing the lens. NOTICE This lens is powered from the camera. The stabilizer unit will be placed to a specific position in the lens body and then shooting will be possible (stabilizer unit will switch to active status) regardless of the OS Switch position. The active status will take approximately a minute from turning the camera on or depressing the shutter button "half-way". The image in the viewfinder looks like it is vibrating after the camera is turned 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. (fig. 5) 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. This is not a malfunction. If you fix the camera with the tripod or another method, please determine the composition when the stabilize unit is in the active status. The composition seen through the viewfinder will be different depending on the power status of the camera. If the active status is cancelled, please press the shutter button "half-way". SETTING THE EXPOSURE MODE The sigma lens functions automatically after mounting to your camera. Please, refer to the camera instruction book. 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. FOCUSING AND ZOOMING For autofocus operation, set the focus mode switch on the lens to "AF" position. If you wish to focus manually, set the focus mode switch on the lens to the "MF" position. You can adjust the focus by turning the focus ring. To avoid damaging AF mechanism, please do not turn the focus ring manually while in the autofocus mode. [. . . ] When you use the lens in the rain or near water, keep it from getting wet. It is often impractical to repair the internal mechanism, lens elements and electric components damaged by water. Sudden temperature changes may cause condensation or fog to appear on the surface of the lens. When entering a warm room from the cold outdoors, it is advisable to keep the lens in the case until the temperature of the lens approaches room temperature.
