Hey guys. I have a D80 w/ 18-200mm nikkor. The only modes i use on this camera is Aperature, Shutter, and Manual. I refuse to use the auto functions because i would like to better myself. But there is one thing i use which im not so sure about. Its the Auto ISO function. I shoot indoors and out all the time switching back and forth and I have no time to mess with ISO settings. I just wanted to get the forums feed back and see if alot of folks use AUTO ISO. BTW, my maximum sensitivity on auto is 800. Is auto ISO a dumbass setting?
