Focus Limiter
You can select the auto focus search range between Full and Limit using the Focus Set Button.
[Full]: Search from minimum object distance to infinity
[Limit]: Search from the selected distance to infinity
* When choosing [Limit], be aware the indicated distance is an approximate value not an actual distance.
* It is recommended to use the auto focus search range limit function at telephoto range. In general, the wider angle range will have deeper depth of field. When shooting with the focus limit function at a wider focal length, be aware that your subject may be determined “IN FOCUS” within the depth of field range. (Closer than the limited range)
* This function is NOT available when using MANUAL FOCUS operation.
