[. . . ] Enjoy your new Sigma camera! SPECIAL FEATURES OF THE 170-500MM F5-6. 3 APO Powered by Foveon X3 technology. Uses a lossless compression RAW data format to eliminate image deterioration, giving superior pictures without sacrificing original image quality. "Sports finder" covers action outside the immediate frame. Dust protector keeps dust from adhering to the image sensor. [. . . ] Even under strong back lighting or complex lighting situations, the camera will give you the correct exposure. AVERAGE METERING The camera will measure the average brightness of the entire scene with additional emphasis on the center area. It will determine the most suitable exposure with respect to lighting conditions. CENTER AREA METERING The camera will measure the brightness only inside of the circle as shown in the viewfinder. This mode is suitable when you wish to set exposure for a portion of the scene and ignore the influence of rest of the scene. 53 AE LOCK The camera will fix and memorize the exposure value, while you press the "AE" Lock button. When you wish to lock the exposure of a subject off-center, AE lock is very useful. Use of this function with Center Area Metering Mode is recommended. 1 Center the subject inside the viewfinder, then press the shutter button "Half-way". 2 Keep shutter button "Half-way" depressed, and then push the "AE" lock button. (While operating the AE lock, the displays of the shutter speed and aperture value in the viewfinder are locked and "AEL" is visible). You can release the shutter button. 3 Hold the AE lock button while you compose the picture. Then press the shutter button to take the picture. When the subject is out of focus during AE lock operation, remove your finger from shutter button and press the shutter button "Half-way" again, or remove your finger from the AE lock button and restart from the beginning. 54 EXPOSURE COMPENSATION If you want to intentionally overexpose or underexpose the picture, use this function. While pressing the Exposure Compensation button, turn the "C"-dial to set the desired compensation value. Then, release the Exposure Compensation button. The LCD panel will show " compensation button. The " underexposure. 0. 0" when you initially press the exposure " indicates overexposure, and " " indicates Exposure compensation can be set in 1/3EV increments from +3. 0 to ­3. 0 stops. For example, if you set +1. 0 then the shutter speed will be one stop slower in Aperture Priority mode. If the "D"-dial is set to the continuous shooting mode, the camera will expose only one frame for each activation by the remote controller. The remote controller may not work properly if strong sunlight is shining directly on the camera's remote control sensor. The camera will switch itself off after about 5 minutes of inactivity, while in the remote control mode. To reactivate the camera, press the shutter button "half-way down"; the remote control mode will work again. The light entering the viewfinder can affect the exposure system of the camera. To prevent this, use the finder cap while using the remote controller. USING THE MIRROR LOCK-UP WITH REMOTE CONTROL When using mirror-up mode with the remote controller, we recommend that after adjusting the focus, fully depress the shutter button of the camera once, to lock-up the mirror, and then release the shutter by remote control. This procedure saves your time. 1 Set the "D"-dial to "UP" position, and set the remote control mode. 2 Press the shutter button "half-way" to focus on the subject, and 3 set the desired exposure. Then press the shutter button "all-way down" to raise the mirror-up and retain the focus and exposure. To take the picture, point the remote controller's transmitting diode at the camera and press the transmit button. REPLACING THE REMOTE CONTROLLER BATTERY Use two CR 1220 3V Lithium coin type batteries. 1 2 3 Remove the bottom cover screws with a screwdriver. Open the bottom cover and replace the batteries.
