ISO-speed settings
Flexible ISO speed settings and a new ISO speed bracketing function.
Unlike a film camera, a digital SLR’s imaging sensor’s ISO sensitivity can be altered freely from shot to shot, depending on the lighting and desires of the photographer. The EOS-1D provides a normal ISO range of 200 ~ 1,600 in 1/3-stop increments, and a Custom Function expands this range between 100 and 3,200.
Another new professional control - ISO speed bracketing - allows the photographer to keep the same shutter speed and aperture settings, and have the EOS-1D alter the ISO sensitivity to vary the exposure. Finally, Custom Function 8-1 and 8-2 allow the user-set ISO speed to be displayed in the camera’s viewfinder. |
