Precision focus
The camera supports the precision focus feature which is offered by some advanced
(digital) lenses. This system automatically focuses the image within a user defined focus
frame on the screen. When precision focus is enabled on the lens, the focus frame is
superimposed on the viewfinder image. The frame can be moved and resized by the
controls on the lens or on the focus handle.
An indicator in the bottom left corner of the viewfinder screen shows the current focus
information:
Refer to the documentation of the lens manufacturer for more information about the
precision focus feature.
Lens indicators in the viewfinder
The RE indicator in the viewfinder lights when a lens range extender is selected.
The Iris indicator in the viewfinder shows the value of the iris opening (when enabled in the
