10Shooting techniques for different targets (continued)Shooting using the FUNCTION knobThe following types of recording can be carried outusing the FUNCTION knob.Area auto focus function•Operates auto focus within an area frameselected using the FUNCTION knob.Area auto iris function•Automatically adjusts the iris value within an areaframe selected using the FUNCTION knob. Thisfunction cannot be set when the FACE DETECTfunction has been set.Area luminance display•Displays an averaged luminance level within anarea frame selected using the FUNCTION knob.1 Select the function from the FUNCTIONKNOB option (page 53) on the settingsmenu SW MODE screen.FOCUS: Area focus function and area focusbar function (during MENU setting)IRIS: Area iris function and area iris meterfunction (during MENU setting)YGET: Area luminance displayFOCUS/IRIS:Simultaneous operation of the areafocus function and area iris function,simultaneous operation of the areafocus bar function/area iris meterfunction (during MENU setting)FOCUS/YGET:Simultaneous operation of areafocus function and area luminancedisplay, simultaneous operationof area focus bar function (duringMENU setting)2 Press the FUNCTION knob.A white frame is displayed.•There is no change in the operation of the•camera other than the display of the frame.3 Press the FUNCTION knob again.The white frame turns yellow.•When the frame is yellow, the FUNCTION•knob function set via the MENU operates inthe area inside the frame.Pressing the FUNCTION knob once more•returns the yellow frame to the white frame.Switching AUTO/MANUAL for FOCUS/IRIS•is normally carried out in the same way.The central luminance function does not•operate when the area luminance display isoperating.If the FUNCTION knob is held down for more•than 2 seconds, the frame disappears andthe area function is switched off.4 Move the FUNCTION knob up and down,and right and left.The white frame changes position. Move the•frame to the area you wish to select.The area function does not operate during face•detection.The area function exits when the power switch•is set to OFF or when the camera is switchedto playback mode.Auto focus and auto iris may not be available•depending on lens used.The area luminance, FOCUS BAR, and IRIS•METER functions are available regardless ofthe lens used.
