49 Setting the Shake Reduction Function The [Shake Reduction] menu appears when the camera is turned on with the Shake Reduction switch on and a type of lens that does not support automatic acquisition of lens information such as focal length (p.47) is mounted. Use the [Shake Reduction] menu to set the [Focal Length]. • [Focal Length] cannot be set manually on the [Shake Reduction] menu when using a lens that supports automatic acquisition of lens information such as focal length because [Focal Length] is set automatically. • Set [FI with S lens used] on the [A Custom Setting] menu to [Available] to enable the focus indicator when using a screw mount lens. If this is set to 3 [Unavailable], the camera assumes there is no lens attached, and the Shake Reduction function cannot be used. • When using a lens without the s position on the aperture or with the aperture set to a position other than the s position, set [Using aperture ring] on the [A Custom Setting] menu to [Permitted]. Basic Operations 1 Use the four-way controller (op) to set [Focal Length]. Select from the following 34 focal length values.
