[QUOTE="hark, post: 749742, member: 13196"] I'm only responding because you mentioned wanting to learn. Take a look at the EXIF data in the series of Great Blue Heron images. The aperture and shutter speed are constant, but the ISO value changes. It would be almost impossible to change the ISO value manually that quickly with a succession of images. Plus something to keep in mind - when in Shutter Priority, the aperture is the value that changes to maintain exposure. In all of these, the aperture and shutter speed don't change. So it seems as though he's using Manual Mode with Auto ISO, but bluzman can tell you his settings for sure. With the last image of yours in this thread, look at your shutter speed (well...the forum sometimes botches the way it is displayed). It appears to be 1/125". That is too slow for moving birds. Increase your shutter speed to 1/2000" and that should help keep moving birds in focus. In bluzman's images, his shutter speed is even faster at 1/3200". Hope that helps a little until you hear from bluzman. :) [/QUOTE]
