[QUOTE="WayneF, post: 249225, member: 12496"] Yes, the Auto ISO menu in the camera (see camera manual index). However, then Manual exposure is not manual. The settings are manual, the selected aperture and shutter speed are manual choices, but Auto ISO makes the exposure be automatic. Say you set f/8 at 1/400 sec. The correct exposure has good odds of NOT being f/8 1/400, so Auto ISO simply adjusts ISO so that it is. There would be no advantage over say camera A mode and f/8. Instead of raising ISO to crazy extremes, it would simply change shutter speed. Camera P mode is probably what you want - you can rotate the dials to alter the setting it will use (still correct exposure). Sports photography fans do use Auto ISO with camera Manual however. They think it is important to specify one aperture and shutter speed, at the cost of whatever ISO will do it. But IMO, for general work, ISO selection is more important that that. [/QUOTE]
