I am not sure whether it does. I guess the longer FL system will be the same as a cropped shot from the shorter FL system. When you bin 2x2 are you over coming the shot noise better? When I was reading Ron Wodaski's astro processing book there was a chapter that spoke of when you bin 2x2 you may pick up details you don't see at bin 1x1 due to overcoming the read noise or effectively increasing s/n ratio. If you don't lose any resolution as in the two systems described could be a worth going for longer FL at 2x2.
