Awhile back I changed my ISO setting to only use 200, 400, 800, 1600 and 3200. I cannot, for the life of me, recall how I did this and how to change the settings back so I can use the ISO settings in between and it is driving me nuts. Does anyone know how to do this? I did reset my shooting menu to factory setting but it did nothing to change this.
Thank you for your help!
