18-55mm "Verse's" 28-135mm image sharpness comparason. how do the standared lens compare with the 28-135 is usm lens for quality of picture sharpness?....is there much difference puting aside the image stabaliza and usm motor drive in the 28-135mm. i need somthing better than the standared lens but dont have the funds for the "L" series and i would like it to be able to zoom, im not after the prime lens types. any help would be much appreciated.
cheers,
