User manual SIGMA 70-300MM F4-5.6 DG OS

[. . . ] To avoid damaging the lens, be especially sure to place the lens with its front end down while changing the lens. 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 on or turned off. [. . . ] Zooming Rotate the Rubber grip on the zoom ring to the desired position. Using the Optical Stabilizer function it is possible to get sharp results at shutter speeds approximately 4 stops slower than you could without using the OS function. Press the shutter button halfway down, confirm the image in the viewfinder is stable then take the picture. (It takes approximately 1 second to produce a stable image from the time of depressing the shutter button halfway). Do not use the Optical Stabilizer in the following situations: When the lens is mounted on a tripod. The Optical Stabilizer function is powered from the camera. If you are not using OS, please turn OFF the OS switch, in order to prevent unnecessary battery consumption. Be sure to turn the OS switch to the OFF position before attaching or detaching the lens to the camera. The OS continues to operate after you release your finger from the shutter button, as long as the exposure meter displays the exposure value. Never remove the lens or remove the camera’s battery while the image stabilizer is operating as this could damage the lens. Although the viewfinder image may appear to shake immediately after shooting and/or at the start of the flash charge cycle of the camera’s built-in flash, it will not cause any effect to the pictures. For Sony and Pentax mounts, it is only possible to use the OS function, incorporated in this lens, with camera bodies which support motors driven by ultrasonic waves such as HSM. When using the OS function, please turn off the optical stabilizer function of the camera body and set the OS switch of the lens to ON. When using the camera’s optical stabilizer function, please set the OS switch of the lens to OFF and turn the camera’s optical stabilizer function on. 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. Attach the hood and turn clockwise until it stops rotation. 3) 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) F11 DEPTH OF FIELD SCALE The depth of field scale helps you to check the depth of field (the zone of sharpness) of your composition. [. . . ] 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. 5 x124mm Peso 610g Dimensions and weight include the SIGMA mount.
