Adjustments and Settings for Recording Setting the Electronic Shutter This section provides a description of the electronic shutter, together with setting and handling directions. Shutter Modes The table below lists the shutter modes in which the unit's electronic shutter can be used as well as the shutter speeds which can be selected. To use the fixed shutter speed To use the half shutter speed (HALF) For eliminating flicker due to lighting For shooting fast moving subjects clearly For shooting images when adding effects as if taken with film To use the shutter speed of SYNCHRO SCAN For shooting monitor screens in a way that minimizes the pattern of horizontal lines For shooting images when adding effects to the subjects' movement SYNCHRO SCAN: Shutter is set using angle (deg) irrespective of frame rate. SYNCHRO SCAN2: Shutter is set using time (sec) irrespective of frame rate. Notes No matter in which mode the electronic shutter is used, the higher the shutter speed, the lower the camera's sensitivity. When the aperture is in the automatic mode, it will increasingly open and the depth of focus will become shallower as the shutter speed is increased. By setting the shutter speed on the time axis (1/60, 1/100, 1/120, 1/250, 1/500, 1/1000, 1/2000), the frame rate can be varied while keeping the exposure constant. This is equivalent to Ramping (compensating for changes in the frame rate using shutter angle) in a conventional film camera.

Corresponds to REC FORMAT option. *2 The "F" of "1/F" is the frequency corresponding to the frame rate when using the VFR function. For example, when the VFR function is used with a frame rate frequency is 15, the variable range of the SYNCHRO SCAN is at 1/15 or more. 53 Adjustments and Settings for Recording: Setting the Electronic Shutter
