I just switched from Nikon D200. I'm looking for a setting which will allow me to shoot aperture priority but which will maintain the shutter speed at a set minimum by adjusting the ISO as needed (auto ISO.) I can see the ISO automatically increasing so there seems to be some sort of auto ISO. But it doesn't start until shutter speed is too long, which makes it entirely useless.
It was my goto setting on my D200; I can learn to live without it if I must but am I just missing it somewhere? How can I tweak minimum speed?
