considering either lens.... 24-70 newer but 28-70 got aperture ring. let me think consider some more :bsmilie:
If you are gonna stick with digital only (or F5/F6) then MTL, get the 24-70 :thumbsup: I have got not much money and may get a F3/FM3A to fool around with in the future, so I will be getting the 28-70 for compatibility.
