Me again!
On the ff 5MK II, 28mm is about as wide as you can go without experiencing some curvature. The 24's give a wider field of course, but one starts to notice distortion in the corners. Its not too bad and can easily be dealt with by sorftware though.
A zoom lens will not give anywhere near as good result as a prime lens and shooting wide open is not usually a good idea with faster primes. In both cases you will notice "blobby" stars though you will decrease the chance of star trails (if shooting un-guided) if shooting at maximum aperture.
Hope this helps.
