I am looking for a zoom lens for travelling. It is either 24-70 mk ii or 24-105. 24-105 is very flexible however 24-70 have bigger aperture for shallow dof. My question is if i use mostly aperture 5.6 or above to get wide dof, is the 24-70 still have better image quality than the 24-105? I notice that at smaller aperture almost all lenses are sharp.
