    Sharpness is highly subjective and there's a whole bunch of contributing factors to consider before you can conclude if its sharp enough for you. The perception of sharpness can be influenced by the AA filter in cameras. In this instances, sharpening of the image in the post editing workflow is absolute necessary to enhance the image.

    Flat, non-contrasty lighting can also affect your judgement on sharpness so in this case, you just have to wait for better light or adjust the contrast / colour later.

    Then of course, there's the infamous hand shake that induces movement blur. That can't be saved.

    The list goes on.....

    allright.... just tried out some of u guys' tips and realised that the sweet spot of around f/6 is indeed as sharp as it can go..

    i guess anymore and it's the lens. Will use pp to practise sharpening too!

    thanks for the advice =)

    Looks like you need help on your basics.

    One simple way is to scroll your aperture dial and you'll see why.

    This is the mathematical representation.
    (square root 2)^1.666667 = 1.8 (approx)
    Hence if you want 2 full stops, 1.666667 + 2 = 3.666667
    (square root 2)^3.666667 = 3.5 (approx)
    The best things in life are free.
