On the Pentax K5 If you are using a 300mm f4 lens and shooting birds simply set TAV, your f-stop to f4 shutter speed to 1/1000s .....iso will change accordingly to the minimum iso and max iso you set. In this case you don`t care about the iso but do care about the shutter speed of 1/1000s since you are hand holding and want the f4 aperture for narrow dof and to help keep auto iso in the minimum range. Yes I could use S mode set 1/1000s with auto iso but that wouldn`t guarantee f4 . Nor would A mode guarantee a 1/1000s shutter speed...unless you fiddle with manual iso constantly.
