Overall - I would not describe by results as 'soft', so I am wondering whether your focussing is as discerning as it could be. Just before you take the picture, press OK and then turn the WHEEL to get the focus area down to a smaller size ..... see if that makes any difference to your close up shots.
(you might know that already ...... in which case sorry!)
