If you want to compare the 24-70mm lens to a 24-80 lens with a special macro-like optics and a manual focus ring,

All of those lenses have focus-by-wire manual focus rings.  Max magnification is .3x (12-40) vs. .2x (24-70).  There is still 1-stop of DOF control missing from the 12-40 or 12-35.

Right the Olympus has a longer focal length and greater range as well as being capable of greater magnification.  It also has as DP Review explains, "a focus ring that engages manual focus mode and reveals a distance scale".

If you want to compare to that lens go ahead, but thanks for acknowledging that there is a smaller lens available to those who desire small size with matching focal range and built-in IS that is also weather sealed and very highly rated.
