    1. If u can.. use a tripod or rest the camera on a stable surface.

    2. Use timer to take the pic.

    3. Use the "macro" mode of the camera.

    4. Even if it's in "macro", there is still a min focus distance.. Do take note.

    5. Dun use camer built-in flash.. Try to use diffused light

    Are you sure you are far enough for focusing properly? When I use my +4 on my S602, I need to be abt ~25cm away in order to be able to auto focus. Perhaps try moving further away to cure your "blur" problem?

    Also, do NOT use the macro mode with the close-up filter. I think the camera won't be able to focus in macro mode with the filter on.

    >>1. If u can.. use a tripod or rest the camera on a stable surface.


    yeah thanks, using a tripod

    >>2. Use timer to take the pic.

    using this too

    >>3. Use the "macro" mode of the camera.

    using this too

    >>4. Even if it's in "macro", there is still a min focus distance.. Do take note.

    i think its 16 cm for the lens. so with 4x its 16/4 = 4?
    i read some thread wch explains that filter does not alter minimum distance, it juz maginifies. logically sounds true. any1 confirm? shud i focus from 16 cm?

    >>5. Dun use camer built-in flash.. Try to use diffused light

    i use a standard 100 w yellow light bulb on top. too bad for a40 that cannot use external flash as for the built in flash, with a filter on a40, the flash is blocked

    thx alot, ur post reminded me of the focal length point. i go back now and try with around 20 cm.
