i mean, if it were any sharper, would you want it to be? the backgrounds are just so easy on the eyes with the 58G which what totally gets me to keep staring at images for long periods of time. nothing strains my eye, its gently pushes my eyes to the subject in focus and just provides an overall pleasing experience. not a whole lot of lenses do that for me...the ones that do cost north of the 58G.
