Under artificial light, particularly fluorescent or mercury lamps, the light intensity may appear to be constant, but the strengths of each of the R, G and B colors are actually changing in synchronization with the frequency of the power supply (“flicker”). Using an electronic shutter under such lighting could make the flicker even worse. Color flicker is particularly likely to happen when the power supply frequency is 60 Hz (with the 59.94I format model) or 50 Hz (with the 50I format model).

However, if the power frequency is 50 Hz (with the 59.94I format

 

model) or 60Hz (50I format mode), setting the shutter speed to 1/100

4

or 1/60 can reduce this flicker.

When a bright object is shot in S-EVS mode or ECS mode in such a manner that it fills the screen, the upper edge of the picture may have poor quality because of an inherent characteristic of CCD. Before using S-EVS mode or ECS mode, check the shooting conditions.

You can turn on or off the S-EVS mode on the SW STATUS page of the PAINT menu.

4-2-2 Selecting the Shutter Mode and Speed

Use the SHUTTER selector to select a shutter mode or a standard-mode shutter speed. To set the shutter speed in ECS mode, with the SHUTTER switch set to ON and the ECS mode selected, use the MENU knob for adjustment.

You can use the SHT ENABLE page of the OPERATION menu to narrow the range of choice in advance, or to select in advance whether or not you use ECS.
