    You should consider stopping down your f value for sharper images

    At such short focal lengths, the depth of field should be sufficient for those pictures.
    Can see that the ISO is already super-high. Stop down some more, and the shutter speed will have to be reduced.... lagi worse.
    Exploring! :)

    True, some says that to get sharper image "stop down" Agreed. Suggest you:-

    1. Use flash
    2. Get a tripod
    3.Buy a faster lens F1.4 or F1.8 type
    Enjoy your every moment with our nature and friends

    what do you guys mean by "stop down", i normally use low f number to try to get the bokeh effect, is this means "stop down" ?

    To me, the Chinatown shots are alright. Sharp enough.

    But for the Botanic Gardens shots, I think the problem is the focusing distance between the lens and the subject.
    That's why it's OOF.

    Others pls correct me if I'm wrong.

    opposite.
    Stop down means to INCREASE the f-number, which causes the aperture to be smaller. This increases the depth of field and reduces the "bokeh effect" (wrong use of the term).
    But this reduces the amount of light entering the camera. Thus you have to reduce the shutter speed correspondingly to compensate. This increases the chance of camera shake in your hands.
    So it's a bad choice in your case. The suggestion to stop down to IMPROVE sharpness will actually MAKE IT MORE BLUR.

    if your friends happen to be pixel peeper breed, ignore them. they will never be happy.

    anyways, sharpness has more to do with lens, so i see a sharp photo, means the lens is ok. doesn't mean i looked at all.

    there are other factors like handshake, movement in the elements in the picture themselves, the list of things that can make a picture "not sharp" seemingly can go on and on.
    Agree on this, sometimes don't be too worried about sharpness, after a few times you will know how to get better photos.

    You may also wish to increase the sharpness level to 4 and try.
