Adjusting Sensitivity Shooting Mode Sensitivity increases the use that the camera makes of available light, allowing faster shutter speeds to be employed. However as sensitivity is increased, the picture may become noisy. Standard sensitivity is equivalent to film ISO 100. The camera will automatically increase sensitivity in low levels of ambient lighting if set to AUTO. The sensitivity can be increased manually from the standard value to allow faster shutter speeds in low light. Set the Mode dial to , then rotate the Command dial while pressing the sensitivity button until the desired sensitivity value is displayed. Notes: Sensitivity Setting • Manual adjustment of Sensitivity is only possible in mode. When the Mode dial is set to after Sensitivity is set, the setting temporarily is canceled and the camera automatically selects AUTO setting. If the Mode dial is set to again, the previously adjusted Sensitivity returns. • When the Sensitivity is set to ISO 200, 400 or 800, or Sensitivity is automatically increased in dark conditions with AUTO, a noisier image compared to standard Sensitivity may be recorded. • In normal shooting situations, 400 or lower Sensitivity setting is recommended. Use the 800 setting in a situation such as when you want to avoid effects of camera shake by using a fast shutter speed. When using 800 Sensitivity, it is recommended that you turn off the Image Sharpening (p. 114) in Shooting menu.
