50Shooting FeaturesExposureThe procedure for shooting images at the desired brightness (exposure) byadjusting the shutter speed or aperture value is called “determine exposure”.The sense of dynamism and amount of background defocus in images to beshot vary depending on the combinations of shutter speed and aperture valueeven if the exposure is the same.Adjusting the Shutter SpeedIn B mode, the range is from a maximum of 1/4000 to 15 seconds.In D mode, the range is from a maximum of 1/4000 to 60 seconds.See “The Control Range of the Shutter Speed” (A 53) for more information.Adjusting the Aperture ValueIn C and D modes, the range is from f/2 to 8 (wide-angle position) and fromf/4 to 8 (telephoto zoom position).C Aperture Value (F-number) and ZoomLarge apertures (expressed by small f-numbers) let more light into the camera, andsmall apertures (large f-numbers) let less light.The aperture value of the zoom lens of this camera changes depending on the zoomposition. When zooming to the wide-angle position and telephoto zoom position,the aperture values are f/2 and f/4, respectively.• When Fixed aperture (A99) is set to On, zooming can be performed withminimum changes in the aperture value.Faster 1/1000 s Slower 1/30 sLarger aperture (Small f-number)f/2Smaller aperture (Large f-number)f/8
