It seems to me that the camera makers are just as slow to accept ISO as an equal to shutter and aperture as photographers are. Why don't cameras have auto-ISO as well as auto-shutter speed or auto-aperture? Set any two and the third one is set by the light meter. Or even any one and the other two go to an intelligent 'Program'. Seems that this would be of more value than another 'creative scene' setting. - TF
