Hi Folks, Just bought my GXR and an M mount. I'm going to be using Minolta Rokkor 40mm 2.0. But the problem I am having is setting the Auto ISO. Usually, when you set auto ISO, you specify a minimum shutter speed and a maximum ISO. I'm having trouble setting the ISO. The manual suggests, for instance, that different auto levels can be set such as Auto 800. But I can't find any such option that looks like this. Can someone help? Thanks for your help.
