This to me is also an advantage to using lower ISO's... than maybe you'd think you'd even need. A high iso small format capture makes of an image which needs to be sharpened very very carefully; as you can go to far and the next day you look at it and you realized you have to redo it. Unless there is a layer in Photoshop for sharpening. Which I'd think there easily could be.
