USING THE FOCUS LIMITER (Ref. Fig 9)
When the focus limiter knob is set to "LIMIT", the camera can be autofocused with greater
speed within that range.
For range from maximum close-up to infinity
Set the focus limiter knob to "FULL"
For close-ups (0.29m to approx. 0.4m)
Set the distance scale to a point between 0.29m and 0.4m, and then set the focus limiter
knob to "LIMIT".
For normal photos (0.45m to infinity)
Set the distance scale to a point between 0.45m and infinity, and then set the focus limiter
knob to "LIMIT".
* When shooting close-ups with the focus ring set between about 0.40m and 0.45m
the focus limit knob cannot be set to LIMIT.This is due to the camera's mechanical system.
